The method as recited in claim 2, wherein the act of installing the remote diagnostic trace listener with a filter comprises an act of installing a filter to filter specific categories of diagnostic traces from the broadcast diagnostic information. 4. The method as recited in claim 2, wherein the act of installing the remote diagnostic trace listener with a filter comprises an act of installing a filter to filter specific severities of diagnostic traces from the broadcast diagnostic information. 5. The method as recited in claim 2, wherein the act of installing the remote diagnostic trace listener with a filter comprises an act of installing a filter represented by an Extensible Markup Language expression. 6. The method as recite in claim 1, further comprising:an act of configuring a diagnostic service to take an automated action when the portion of broadcast diagnostic information matches specified criteria;an act of detecting that the portion of the portions of the broadcast diagnostic information matches specified criteria; andan act of automatically performing the automated action in response to detecting the match. 7. The method as recited in claim 1, wherein the act of boot strapping a diagnostic control application to the external component comprises an act of downloading an installable application to a computer system of a diagnostic user. 8. The method as recited in claim 1, wherein the act of boot strapping a diagnostic control application to the external component comprises an act of downloading a web application to be run in a web browser of a diagnostic user. 9. The method as recited in claim 1, wherein the service host communicates on a first communication medium and the diagnostic host communicates on a second different communication medium. 10. The method as recited in claim 1, further comprising:an act of a diagnostic security system authenticating and authorizing configuration of the diagnostic host and providing the portion of the portions of the broadcast diagnostic information. 11. A computer system comprising:one or more processors;a diagnostic host, the diagnostic host being connected to a service host via a computer network, wherein the service host includes a service endpoint configurable to broadcast diagnostic information for the service host, and wherein the service host is configured to interoperate with local diagnostic trace listeners that provide portions of the broadcast diagnostic information to other components for use in diagnosing conditions at the service host;a diagnostic store that stores diagnostic information for the diagnostic host; and one or more storage device having stored computer-executable instructions which, when executed by the one or more processors, implement a method for providing diagnostic information from the service host to the diagnostic host, the method comprising:an act of configuring the diagnostic host to provide a portion of the portions of the broadcast diagnostic information that is of interest in diagnosing a condition at the service host, including:an act of installing a remote diagnostic trace listener as a local diagnostic trace listener within the service host, the remote diagnostic trace listener describing a diagnostic control endpoint that can be used to access and configure the remote diagnostic trance listener, the remote trace listener including a stub component, the stub component configured to:accept diagnostic information from the service endpoint; andsend the diagnostic information to the diagnostic host via the computer network;an act of receiving a connection request at the diagnostic control endpoint, the connection request from an external component outside the service host and outside the diagnostic host;an act of boot strapping a diagnostic control application to the external component in response to the request;an act of receiving one or more diagnostic configuration commands through the diagnostic control application, the one or more diagnostic commands for configuring the diagnostic host to collect and provide the portion of the portions of the broadcast diagnostic information;an act of creating a diagnostic subscription endpoint to provide the portion of the portions of the broadcast diagnostic information to any external components outside of the service host and outside of the diagnostic host; andan act of returning an electronic address for the diagnostic subscription endpoint to the external component; andan act of providing the portion of the portions of the broadcast diagnostic information that is of interest in diagnosing a condition at the service host to the external component, including:an act of the remote diagnostic trace listener recording the portion of the portions of the broadcast diagnostic information to a diagnostic store in accordance with the one or more diagnostic configuration commands;an act of receiving a request for diagnostic information at the electronic address for the diagnostic subscription endpoint, the request having a return electronic address for the external component; andan act of sending the portion of the portions of the broadcast diagnostic information from the diagnostic store to the return electronic address for the external component. 12. The computer system as recited in claim 11, wherein the act of installing a remote diagnostic trace listener as a local diagnostic trace listener within the service host comprises an act of installing the remote diagnostic trace listener with a filter configured to select the portion of the portions of the broadcast diagnostic information that is broadcast by the service host. 13. The computer system as recited in claim 12, wherein the act of installing the remote diagnostic trace listener with a filter comprises an act of installing a filter to filter specific categories of diagnostic traces from the broadcast diagnostic information. 14.
