OK, I admit it. I'm a Distributed Computing junkie. Every time I go to a new platform, language, or environment, the first thing I try to do is figure out everything I can about how to get applications and computers talking to each other. I've been that way ever since college when I got FINGER working on our VAX system without admin privileges. The resultant meeting in the admin offices the next Monday morning wasn't exactly my idea of fun, however.
Rocky Lhotka wrote an exceptional post on what Indigo could mean to distributed computing. It is a great summary of why Indigo could be The Next Big Thing in this space. I also watched the Introduction to Indigo MSDN TV episode. Very well done. Lastly, the reference to Indigo on MSDN contains some valuable information, too.
