[Users] update SpiceX.cab for win client?

The spice.cab from elmarco that is referred to on http://wiki.ovirt.org/How_to_Connect_to_SPICE_Console_With_Portal doesn't exist any more, and I see that spice-space.org has a virt-viewer 0.5.6 for windows out. Any chance of someone packaging it up in a compatible .cab? Or if there's a resource on how to do it, a pointer would be appreciated and I can tackle it. Thanks! -Darrell
