This is my plan for centralizing the net code under the merged client.

First, TMWServ's Net namespace needs to be changed (I vote for TMWserv as the new name). Then a new Net namespace would be created to store references to the specific network back-end needed.

Here are the functions the generic back end needs (organized by type)
