Right. I'm thinking we may want to have an input task on the echo plugin that takes in the <port> <remaining args> and delgates the rest to the run-main task.   We could call this instead and not need any special case-ing/shims in the sbt-server.  Not sure what you think about that, but longer term I'd like to remove the need for most of these shims if we can.   The question is what lets us get there faster/in-time.
