I preprared the patch for connecting to remote server that shows dialog window with address’s and port’s inputs.
It doen’t fix any multiplayer issues but the server shows remote players.

Looks nice, thank you!
I’ll get back to that and commit within a few days (after release).
Also I found that second client freezes at client/CPreGame.cpp:723 while get CMapInfo.
Well… Somehow unused code becomes broken over time. 
Could be something subtle due to changes to map header and serializer.
Patch has been committed in r3406. Thanks!
