How to run linux across two A20 boards

[GRAHAM3551]

Has anyone tried running two linked A20 boards yet?
I have seen reports of people doing this with Raspberry PIs networked via ethernet, but are there other options for Olimex A20 boards?
I am hoping to do this, may be with Arch Linux?, anyone tried?

The idea is as a headless server which can be accessed by another tablet / chromebook, so both boards can run pretty much the same OS / software.
