I can help for Python.
Actually, I even already started. Though I probably won't be able to compete with 55 min every day of vindi, I could help.
Also, it's much easier to start from the beginning, ignore the networking, make ctf and all the classes work (wihout the HUDs first), and then just add stuff.
The collision system could get a little complicated, people on the #pygame channel recommended me to use rects for collision (also with the wallmask), and not mask.
Speaking of which, what library are we using? Pygame, or something else?
