I like the idea of the profile. If I may suggest that we could provide a default profile and provisioning tools (shell commands, and configuration files) that would allow the cluster admin to partition the nodes to profiles and build various topologies.

A would prefer a mixed mode. By mixed mode I mean broadcast changes and pull configuration "on cluster join". This way you avoid unnecessary polling, without the danger of staying out of sync. > I don't see many reasons for stopping a single bundle unless you want > to stop the feature it belongs too. > As a user I agree on that.

I don't see how we are stepping toes with ServiceMix or Camel. Now regarding CXF DOSGi you are right, howeverI never felt that it fits nice inside Karaf, but that's more like a personal taste than a requirement. > -- > Cheers, > Guillaume Nodet > ------------------------ > Blog: http://gnodet.blogspot.com/ > ------------------------ > Open Source SOA > http://fusesource.com > -- *Ioannis Canellos* * http://iocanel.blogspot.com Apache Karaf <http://karaf.apache.org/> Committer & PMC Apache ServiceMix <http://servicemix.apache.org/> Committer *
