[p2p-hackers] P2P in Python and file synchronization

[Michael Rogers]

Hi Alexandre,

You might want to check out Groove (http://www.groove.net), Grouper 
(http://grouper.com) and Shinkuro (http://shinkuro.com). They all allow 
you to create encrypted groups for file sharing and messaging. Groove 
has a pretty sophisticated way of propagating changes to files etc, but 
I'm not sure whether it can be scripted or used to synchronize the 
filesystem (you might want to look at rsync over ssh for that).

Hope this helps,
Michael
