Async Beauty

Wow, came across AsyncWeb today and have to say it's a thing of beauty. Excuse me while I tout my own greatness for a while but about two years ago I had an idea to write a NIO/async REST engine for wicked fast, non-servlet cruft, async REST implementation and AsyncWeb + RESTlet is headed in that exact direction. RESTlet is equally impressive and has come a long way over the last six months. Love the pluggable connector design for RESTlet, should really allow it to move in ways that the Servlet spec hasn't been able to.

If you are trying to do things like COMET with traditional threaded servers, you're absolutely mad and need to look at this approach.
