VDI should be a kernel module. The main reason for this is speed. 
AES should be a userland app. I see strong reasons fro adding XGem to 
it (ie. AES+XGem hybrid)

Some time agor Frank made (or tried to make) kernel module from 
Xaaes. Frank, you never said what was the results of it, could you 
tell us a little about it?

The other way could be having both VDI and AES as kernel modules, and 
AES should call VDI directly (ie. without using traps). I think this 
is the fastest solution (CPU wise) and also could save some work.

We could beat MagiC ;)
