I am aware that there is some hardware out there with support for this.
But most desktop users will not want to use a fairly highend server as
their desktop machine. So I should have qualified my answer with "It's
not available today for desktop machines"...
>From what I can read, the x366 doesn't even have PCI-e slots, which
would reduce it's usefullness for the average gamer to near zero, and as
the original post was about playing games on a desktop machine, it's
still not particularly useful, even if the OP would accept a server as
their desktop machine... ;-)
I'm looking forward to seeing your presenatation at OLS.
