If you really wanna share..ill help with what little I have, but its gotta be online... 

Start with SSH and the commandline :) remote login, I can spare a server for that and create accounts for anyone willing to invest time. :) Start a google group, get a project, share code via SVN and blah blah...possibility is endless. I am currently teaching two of my friends the same thing.

We dont have to meet up physically as everything is learnt via a remote terminal. 

PeaceSoul..maybe something like that would be more helpful? Just a thought.
