Richard has an i2c and spi driver for t= he pi. I grafted the inferno i2c file system interface on top of Richards dr= iver, though the sub addressed reads are awaiting my return from holiday.
there is a pi gpio and pwm driver which has a pi audio module which sit= s on top. this produces strange noises with a pi2 which I will dig into shor= tly.

I think the pi is a wonderful terminal, the on= ly app which would really benefit from Gbit ether is Remote Desktop (imho)

I would love a similar machine with Gbit ether and 2= or 3 sata 3s to replace my ageing file server.

Arduino Y=C3=BAn (MIPS+AVR) could make a= cool device for Plan 9, but the MIPS part of the hardware is closed.

On the smaller end of the scale, I've just started po= rting lib9p to esp8266. I'm using ESP01; it is a cheap yet very capable devi= ce.
