Richard has an i2c and spi driver for the pi. I grafted the inferno i2c file system interface on top of Richards driver, 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 sits on top. this produces strange noises with a pi2 which I will dig into shortly.

I think the pi is a wonderful terminal, the only 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.
