I've only ever used Git with Unity and as long as we're disciplined in our process, it's not a problem. It's free, scales to any size team for free, and lets us open source our projects easily.

I would be willing to consider Perforce, but it seems very expensive.

What is the industry standard means of open sourcing a Perforce repository?

I should also point out that learning all of ASL isn't necessary for it to be helpful. "Yes", "No", and "Thank you" are pretty helpful on their own.

Sign language is a pretty good option. There will be times when access to the technology used to produce her voice might be inconvenient or even unavailable. American Sign Language (ASL) is also probably much faster than typing in a lot of cases. I grant, this probably won't be as helpful out in the world where most people won't understand it, but in the comfort of home, being able to converse at the dinner table without a keyboard at your side might be preferable. I suggest you don't ignore this as a supplimental tool.
