I hope my 2.2GHz does the trick then ;)

I think I'd need to give it a go before I can say whether that would be the 
case here for me or not. However Erwyn has shown that it can handle with no 
problem grabbing the F4 variables, throw them across a network and make 
them available for processing in real time, the Phidgets site gives VB as 
its code source, and I've had no problems running VB DirectX apps at full 
pelt. You may be surprised at how fast a compiled VB exe can be. I can't 
believe that the processing is the bottle neck in such a hardware venture 
that doesn't have any graphical basis to it. But until I try it I can't say 
one way or the other ;)
