I have a question regarding this: Should we aways use JGroups Multiplexor by default, or only when running under JBoss5? I'm creating a new interface to perform JChannel creations called ChannelFactory. This interface is only used at DefaultClusteredPostOffice and its service. Since I don't want to put everything on the same package as DefaultClusteredPostOffice, I have created a new package under postoffice.cluster, called jgroups which can be easily renamed/moved later if that's not the proper place. I haven't committed my changes yet by the time of this post, but I will as soon as I have finished running testcases.
