Open source alternative to FireBase?

[koolkao]

From my limited experience with the tutorials, I'm a big fan of FireBase. I wish I could use their framework and their service. Unfortunately since I'm in the healthcare space, it's a much higher burden to justify, in terms of business and in terms of regulatory compliance, entrusting so much protected information to an outside entity.

Are there alternatives similar to FireBase that we could host on our own servers?

Take a look to the Atmosphere Framework: http://www.ncolomer.net/2012/03/cometwebsocket-introducing-t...

Meteor?

Or just roll your own using WebSockets (perhaps using socket.io or Faye to make it easier).
