Not that I think it entirely bursts your internet tough guy rant, but amazon does offer [cluster computing instances](http://aws.amazon.com/ec2/hpc-applications/ http://aws.amazon.com/ec2/hpc-applications/) for exactly this purpose. Granted, they only have 10 Gigabit ethernet, but it's not exactly like this is some failure cluster running all over a busy datacenter on 10M ether.
