Linux4nano also has a fairly active IRC channel, #linux4nano @ irc.freenode.net. #linux4nano-dev is the channel for developers. IRC logs are located here (password protected). Info about this wiki can be found at the About page.
Status at a glance: Further improving iBugger, and working on audio drivers. iBugger can now run the Rockbox bootloader without hitches. Working on injecting code into an iTunesDB file for the other generations.
