If this idea got combined with the virtual SAN switch idea, you could do
quite a bit with it. The SVC microcode already understands iSCSI and if
I understand the innards well enough, we'd just need some new device
drivers inside the SVC virtual machine to handle however z/VM presented
the virtual SAN interfaces and devices, which is a much less daunting
task. 

Hmm....
