As a mid-term move for CryptoCat "server side" it would be nice to make 
it's own minimal and secure XMPP Server, to be installed without any 
configuration burden, be "secure by design" and not necessarily "by 

Doing so, would facilitate the integration with Tor to easily let anyone 
startup it's own CryptoCat server (also on windows/macappstore), running 
over TorHS, making the architecture more distributed and SSL-free.

A nice set of technology to do it could be:
- Wokkel, XMPP Server based on Twisted http://wokkel.ik.nu/
- TxTorCon, to manage Tor process https://github.com/meejah/txtorcon
- Pyinstaller to make windows/macosx package http://www.pyinstaller.org/
- Cyclone, to make web interface to manage it easily
