Can't remember if I replied to this..
Anyway no it does not use Mumble link, but my own source very similar to the default plugin template provided by Thorvald Natvig but much more simple.
Yeah no source code as of yet. Not proud about the few lines of ASM I've used to save time, overall it's a very quick and dirty code and I don’t think its pretty enough to publish.
I'm sure if more people show interest I could be bothered to clean it up and publish it. :)
