What do I need to add to make you use this for video chat?

[monvural]

I built a play application this weekend to show off at a Ruby hackathon. It's built using the OpenTok video chat API (full disclosure: I work at TokBox).

I wanted to find out what folks would want in the application to actually use it for their own video chats. It's hosted on a free Heroku instance, and so I doubt performance rocks, but if I need to buy some dynos for folks to test, then let me know and I will.

I just really want to find out what are the features outside of basic video chat that you'd need to use a simple video chat solution like this one.
