Well, since 2/3 of the current source ports can run on Linux, why not have a Linux server browser?
Skulltag currently has no Linux server browser except for a VERY alpha Java server browser with several bugs. Odamex does have one, but with how complicated it is to set up it's easier to just run IDE in WINE.
With a native IDE for Linux, setup and wad paths would work properly, it would be less crash-prone, and it would make things easier for BOTH ports.
Of course since ZDaemon does not run on Linux without extra software, you would only need Skulltag and Odamex buttons. Maybe no need for an IRC client since zrc is buggy on Linux anyway (unless you added a custom one- would be cool, but unnecessary).
