I would like to give my 2 cents to the subject. I spoke with Tom, and I have a (well sort off) working multiplex implementation. It can be found at: http://anonsvn.jboss.org/repos/jbossnative/sandbox/mux/ (although it has nothing to do with the native for the moment) The point is to have a TCP/IP interface over a single socket, thus allowing both TCP and UDP protocols. In essence it's a ssl tunneling without ssl (can be added) and usable via API, not as an OS layer. The entire concept is based on HTTP-NG http://www.w3.org/Protocols/HTTP-NG/ View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979405#...
