Seriously lets take the high frequency trading thing off this list and any one else who wants to talk to me as well a out it, I'm perfectly happy to explain it.Further more I'm willing to explain the real problems with the world financial system but not on this list and certainly not on this thread

Wow I don't know how VMware got mentioned in this string but VMware is
not capable of real time operation and if you ask the senior engineers
