This sounds like a good idea.  I assume we aren't forcing containers to use this mechanism, so if someone want to integrate container X but doesn't initially want to go to this much effort, they can use X's socket listener and change to use Geronimo's in the future (although this migration will impact their configuration).

If we do end up going down this path, it would be worthwhile talking with the Derby project about SSL and authentication for the network server.  AFAIK, this work hasn't been started yet, so it would probably be a good time to talk with them.  See the mail thread from the links in http://issues.apache.org/jira/browse/GERONIMO-842 .
