Another point: it doesn't matter what kind of device (character, block, etc) 
if you're exporting at the PCI level.

In contrast at the virtual device level there's not a standard way of 
exporting a device, although I understand there are some standard means of 
exporting a tape backup device to the network.  If it performs OK, you may 
find it simpler to do this rather than PCI device assignment.

Cheers,
Mark
