I'll post to as7 dev list for help integrating. Just wanted to jump into your discussion here as well :-)
We have only tried running from NetBeans and here it seems that the compiled classes is not automatically copied, but that's probably a configuration issue. We didn't spend a lot of time trying to make it work without sym links though.
We will upload the dev version with JBoss integration soon so that you can take it for a spin.
Yeah, I noticed that JBoss World was around the corner. Have a nice conference :-)
