From what I can read online GHost servers don't need to be explicitly chosen, they just sit there silently intercepting traffic to bring large sites' content closer to visitors. TM will like this sort of thing, because it will reduce load on their overseas connections. Now if only they'd put a few big Azureus servers in their datacentres...

It would be interesting to know exactly how it works - whether redirects are being used, or whether its anycast DNS or something. Not interesting enough for me to find out for myself, mind!
