I guess we can. All items are public in python, so we have full access.
Maybe some tricks required, but should be easy.

Class constructor has list argument, so I guess we can (even in case of
using this plugin as library). If we fork it then we will have full
control over all things, but doubt it's required.

Not sure. But currently there is no such functionality in our git plugin
 (Git folks develop libgit2, so we will be able to switch to it later).

It's availble in OpenSuse, should be avaible in *ubuntu and other
distros. We just need bzr (which is required anywhere) and qbzr plugin
for bzr.

I/we will :)
