Can I use Parse for Real time Social App?

Just noticed Parse and getting excited to see its wonderful features.
Can I use Parse for Time app (like Social App) which requires simulatenous connection and instant notification of changes for all active sessions?
First of all, I would like to say Thank you for this great resource.

Yes with the livequery feature you can build real-time scalable apps ( you can plug a redis if you want).
With livequery you can listen complex events on your ParseObjects without compromising security !
