Me, I was just planning to see how the python-GPIO library does it and make similar Pd externs. But I don't know what I'm doing :)

hi all,
i made a small program which uses GPIO to scan a keypad matrix and send OSC data to pd it depends on liblo and libbcm2835 it's very specific to my project but could help someone... code is here : https://github.com/avilleret/pianophone

Hi Miller,

great, thanks! Meanwhile I found out about webiopi, which can act as a placeholder ATM. (http://code.google.com/p/webiopi/wiki/RESTAPI)
Will you use /dev/mem and require root privileges, or the /sys/class/gpio filesystem? (see http://www.raspberrypi.org/phpBB3/viewtopic.php?f=29&t=9667&p=198848 for how to change permissions, non-standard !)
