Messaging Plugin

I'm having a small problem with the messaging plugin. Clients that call
RegisterClient don't seem to get registered on the server.

How do I troubleshoot this? I've set a breakpoing on the public
bpchProcess procedure in TpsnxMessagingPluginCmdHandler, but it never gets
fired. It seems like the message is getting lost in the transport system
somewhere.

I have two plugin command handlers attached to the same simple command
handler - is that the problem? If so, how do I attach both to the same
command handler?

I guess I'm just asking "where do I go from here"?
