this is my implementation of the piratebox for maemo. tested with n900 and n810 under Diablo and Fremantle.
I also found David Dart's implementation, however his solution requires custom kernel, and mine is much simpler.

It's described at http://norayr.arnet.am/weblog/?p=1909
and in maemo wiki http://wiki.maemo.org/Maemo_PirateBox



you can see this if you'll be around me
