Hi Miller,

I think either I or a grad student (we'll see) will be writing a Pd extern to do this efficiently -- for the moment it would be possible with a Python script (using netsend/netreceive in Pd) but having an extern would be more lightweight and probably more robust.
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 !)
