One of the first questions people will wonder is if it will work with their hardware/software configuration.
Having been bitten by AMD promising GPU IOV being widely supported, i'd probably rate the current support for that as "sad" or very sad !
At the moment this whole thing is a bit of a dark art, and next time I choose HW, I'd like it to be some that works with LibVF.IO, it would be great if I could easily get right from the project page to a place showing current support.
(And once this all kicks off, there is the very very dim hope we can shame AMD into some action themselves).
