The "guest driver interface" or virtual device interface is not yet
implemented, though we expect this to be available over the next couple of
weeks. Likewise, direct device access for domains other than dom0. Primary
documentation will be the header files and sample implementation in
xenolinux :) time permitting we would also update mini-os with some sample
device driver, though they will look a lot like the ones in xenolinux and it
is not quite clear to me how much use they would be without also pulling in
say some sort of a network stack. We plan to write up some of this but don't
yet know yet to which detail.
