The current version of butterfly in karmic does not support file transfers (neither direct or through server).
This is a very important feature so cc myself :)
can you give me your git repository, so I can help you to test?
So, this is pretty much working. It relies on my papyon "direct" branch.
At the moment, all traffic is sent through MSN's servers, which is pretty damn slow, but its a start. I don't really want this branch to get bitrotten.
I rebased on top of master because lots of things had changed. Anyway, it's a start. It's not really merge-ready now, but a review soonish would be nice to get this rolling.
Okay I merged the branch with Louis-Francis and my work in. master depends on papyon 0.4.9 which only has switchboard file transfer, but it's a start. Also, once direct transfers are implemented in papyon, butterfly /should/ need no changes.
We will see.
Anyway, this is fixed.
