Hi Rex, I don't have a good idea how to do something like this in karaf. It would have to work through config admin since any service opening a socket should get the port from config admin (the shell does). So I think we would need some kind of config admin administration tool that would shift all the port values by some constant. I haven't looked into anything about how to implement something like this.
