We can try to see of we manage to raise any interest around it during the Xen 4.4 release cycle.

The spice server used to be part of QEMU/KVM and not available separately, but looking at http://spice-space.org/download.html, now they have an "Xspice" server that probably does exactly what you need. Otherwise implementing spice for PV guests could be non-trivial: spice relies on a virtual graphic card called QXL, similar to a virtio device. Typically Virtio devices work over PCI (even though other transport mechanisms exist), and PV guests don''t even have a PCI bus.
