Yes, 2 Cache instances can share a single JGroups channel using the JGroups Multiplexer. There are sample configs in SVN.
And here's a wiki page with more info on the multiplexer: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossCacheMultiplexer
In a nutshell, with the multiplexer, a single JGroups channel is created and shared among several cache instances. That way, one cache can be configured to use BR and the other can use total replication.
