I think it would have very little chance of being accepted upstream. The xway
TCP-over-Xen implementation would have even less chance of being accepted *as
is* due to making modifications to the Linux network stack.

Yep. If a generic solution using something like virtio is available *and*
there are multiple hypervisors which can leverage it then hopefully it would
have a decent chance of being included.

Dan/Mark:
Thank you, we are creating a proto-type project that may leverage some
of the work.
We will be more than happy to share our results with you and the
community.
Thanks.

The original code was very recently made available on sourceforge under
GPL:
http://sourceforge.net/projects/xvmsocket/
Medium-to-long term though I don't see a Xen specific socket impl as
really
being a viable model. A generic solution based on the new Virt-IO
paravirt
infrastructure will be more appealing to app developers because it'll be
possible to make use of it across all the different impls of
paravirt_ops
in Linux (ie Xen, KVM, VMWare, LGuest).
