I wanted to give another update as to the status of patching Mumble to support native Tor proxification.

Mumble uses its own connection protocol to make external connections, a protocol which is defined in a 30-page pdf file which comprises most of Mumble's documentation (the comments in the code are quite sparse). Most of the methods laid out in mumble-protocol.pdf are defined in the file mumble.pro (or mumble.proto in the github version). I suspect the method named 'connect' of being a culprit in the DNS leaks. Unfortunately 'connect' is not defined in mumble.pro like the rest of the connection protocol. Right now I am searching for where this method is defined. I have visited #mumble on freenode, but no one there was able to offer any insight. I even wrote a simple tool to help me search for this method, but 'connect' is used in over 30 of mumble's *.cpp files (and none of the *.h files).
