OK - that's not so bad. I can interface Jetty to it - no problem. I'm still a little concerned about this centralisation creeping outwards. Are ports the only resource over which different instances of JBoss running on the same box are likely to collide ?
We should also bear in mind that certain services are usually expected on particular ports. Reconfiguring the client side to know where the new port is may be just as important as telling the server side where to listen. You port service will need to allocate/deallocate and lookup ports (and throw PortAlreadyAllocated and NoSuchPort Exceptions). Or is this becoming too complicated ?
