Virtualized TaskBar: A Utility I'd Like

Is there any utility that displays on your task bar all the applications running within your Virtual PC / VMWare / Remote Desktop Session? I'd really like such a utility. It ought to be possible, at least if the virtual machine is network-reachable. If I felt that I could sell more than a couple hundred for \$30 a throw, I'd probably be willing to spend some time writing it myself, but I don't think Windows users spend money on utilities. Mac people apparently buy 3rd party software and PDA users and cellphone users are friggin' ATMs, but you know any utility for Windows is going to end up on P2P before you sell a hundred copies. Whether that actually zeroes out sales, I dunno'.
