vladev- Sure. It's on Github; Written in Python + Tornado. If you're interested, email me.

I'd rather clean it up, but if you're a Python guy, you could help ;)

URL please.

It's really not that ready for public consumption yet, but, I've added you to the project, and made it public.

Thanks :) Actually I asked just to have a look at how this is done. I'll surely help if I can.
