Currently trying to get DriveShare working on a Raspberry Pi. Would be nice to have a low power unit handle farming.
You should take a look a Storjtalk.org, There should be a thread about Driveshare running on a Raspberry Pi.
Done!
https://storjtalk.org/index.php?topic=2206.0 A thread where we can talk about building out on Raspberry Pi.
I'm interested and have one pi and two drives ready to commit. :-)
