I'd be happy to help on this project (I already have keymaps to contribute!).

A SF page would be great, and would provide hosting, IMO (Not my original idea, JohnX proposed it).

EDIT: Also, a way of charging while running Debian would be nice. Maybe it can be stolen from Maemo (I can't BELIEVE that they ditched APM!)?

EDIT2: And a custom kernel with modules people may find useful (such as USB-Ethernet chipsets, maybe USB-VGA drivers, while keeping it compatible with OS2008)

EDIT3 (last one, hopefully, for this post): And for right clicking, the GTK thing is unnecessary. The Zaurus world is using XBindKeys to do it.
