Physically ideally. The one stumbling block there may be is blktap on
ARM - it depends upon a kernel module which is unmaintained as an
out-of-tree dkms, so if there are any problems we may have to find
alternatives, which would involve quite a lot of development.
xenserver/buildroot's storage stack is pretty dependent on blktap right now.

I'd love to have a look at the cubietruck, so please do bring it along!
