Tip: Use multiple PCs Trick:I use 4 virtual Pcs runing on 1 Pc and increse processing time to 5x. It's mine out at best performance. Your can download soft: "Virtual PC" from microsoft website and install it, created some virtual PCs run windows 98 to increase processing times and earn more moneys.
Sounds like a loophole that will get closed soon enough if the GOMEZ people know what they are doing.
I found that in using Microsoft Virtual PC on a network you still need to create a computer name and join a workgroup. Once you do so, the Virtual PC emulates another network card and a new IP address is assigned by the DHCP server. Problem solved.
@ExistentialDesigns: nope, Microsoft Virtual PC uses NAT for internet (like VMware) => all the virtual machines have the same IP as the real machine
