Hi! Tim from Repl.it here.

I used to be an avid c9 user in the classroom as well, but the startup time was killing me.

When is your 8-week program starting? Repl.it can do almost everything you want it to - our editors are fast to load, starting a server is as simple as opening a port, and we're extremely easy to use and almost feature complete. The only thing we're missing is a terminal, which is in the works (the alpha version is released, but may not work for RoR). I just want to get a sense of your timeframe so I can see if we can expedite this feature for you. Let me know if you have any questions!
