For those wanting to start immediately, you can at least download the ear that I've been able to put together so far and that is available from my blog here:

During the last weekend I was able to add the OFLA Demo, the most interesting of them all so far.
Like many of you, the amount of time that I have to dedicate to this is quite small and if any of you could have a look in it, improve it or simplify it would be great. I'm not that good with Spring. Ultimatly we will post an artcle in the Articles section of JBoss.org and provide an example ear to the Red5 team hopping that they will include a ear builder task in they build system. Hopefully, more JBossians will addopt it! :)
