Re: [jboss-as7-dev] Feature requests from bof
Right, I would expect there is a discovery protocol implementation
provided by the as7 integration layer because it probably also has a
clustering subsystem dsl in the domain as well.

This would require JGroups to be plugged with an external discovery mechanism instead of
JGroups doing it via PING/S3_PING/GossipRouter. Maybe just a new discovery protocol to get
the info from AS7 domain API would be enough.
CC'ing Bela/Vladimir which I'm not sure are reading this list.
