Hi,
i've googled around a bit about possible 'global load balancer' setups.
A proprietary thing that does this is Cisco DistributedDirector. It's
not cheap- i've seen a price of 19000$. Nice if Cisco donated one...
However, there seems to be a good Open Source alternative at

I'm into party preparations, have fun tonight!
