If the following sort of "meta-project" is appropriate, feel free to add this too:
Use Python, Twisted and txtorcon for Tor tools language: Python, Twisted Likely Mentors: meejah, as co-mentor
If you are interested in implementing some Tor tool, utility or network research and are considering using Python I would co-mentor your project and provide help and advice to use txtorcon to do so. If there are missing features required to complete your tool, I can either help you write a patch or do so myself.
It probably makes the most sense if your tool involves networking somehow because Twisted is great for that and will then inter-operate well with Tor, too. For non-networking utilities (e.g. parsing various Tor cache files) Stem can be used.
