I'm still working on jingleFT for Gajim (not much progress there). The changes for xep-135 (no progress at all there). A secret project involving i2p (I don't talk about projects before having done a beta. No much progress there either).
The jingleFT branch of Gajim does need some refactoring. I made a state diagram of the file transfer, and it looks awful.
Clearly there are unnecessary states like transport info and proxy activated. The events are somewhat ambiguous, and the states accepted and initialized should be merged into one.
I'll fix it. See if I can shake off being so stalled.
