Maybe a system based on Java or Linux. I am planning to build a new home soon and unfortunately will not be able to incorporate the latest technology with some certainty that I have a long term solution. I will probably just build in some generic backbone capability with no specific controllers or system attached. If Sun and Microsoft were indeed trying to provide the best products to the consumers they would work together on a common best standard for all to use. They are just being greedy with their combative approaches.
Lets hope they can overcome their greed and move into the future with all of our interests in mind.
Don t hold your breath for Sun and Microsoft to start working together. We already have a standard.
