I too am curious about this. As a comparison, I'm using the maven galaxy plugin to auto-publish my WAR's to Mulesoft's TCAT repository through hudson/jenkins auto-builds with very little effort on my part (with a separate process within TCAT's interface to deploy/redeploy from that repository).
Is there similar capabilities for using JOPR/RHQ's repository (originally channel) mechanisms for these kinds of Maven WAR/EAR/SAR generated artifacts (either through a maven plugin, or just pointing to select content sources being maven repos).
p.s. in the case of updated -SNAPSHOT's, how would these be handled? TCAT for example you 'redeploy' the same deployment and automatically get the freshest -SNAPSHOT, which is a resonable expectation.
