we can make a list of the most common cs classes w/ their dev envs. 162 has gdb/c stuff.

what if we tried supporting the bulk of edu dev envs out of the box? we could advertise this as well, which gets ppl to use the lab computers. only drawback is lack of persistent storage, which we should heavily disclose.

we can also add these dev envs to tsunami and its replacement
