For AS 5 Beta 3 I'd like to get the various clustering-related deployments grouped together in deploy, rather than scattered all over the place. Basically you'd end up with:

+---cluster
| | cluster-beans.xml
| | deploy-hasingleton-beans.xml
| | ejb3-clustered-sfsbcache-beans.xml
| | ejb3-entity-cache-beans.xml
| | jboss-web-cluster-beans.xml
| | jboss-web-cluster.aop
| |
| \---jgroups-multiplexer.sar
| \---META-INF
| multiplexer-beans.xml
| multiplexer-stacks.xml
