What kind of areas are you interested/experienced in? What would you like to learn? I'm sure there are tons of gaps out there that you could help fill. Maybe the folks on irc.mozilla.org #rust might be able to give you some ideas.
Thanks. I'll definitely try out irc for some ideas. My general projects are small automation tasks for myself as well as small web-based apps for myself and friends. That's part of why coming up with ideas for something like rust are a little tricky.
The only promising thought I've had is maybe implementing some sort of template preprocessor that I can find a way to work into an existing rust framework.
