There is a open source tool SuperSparrow which is a global load balancing
solution that basically works this way. http://www.supersparrow.org/
(See where it directs you when you go to the above URL).

The blerb is "Super Sparrow enables users to load balance traffic between
geographically separated points of presence by finding the site
network-wise closest to clients. This is done by accessing BGP routing
information, the information that determines the path that traffic will
take on the internet."

I remember that it deals with quite a few of these issues.

There is a paper on the technology
http://www.au.supersparrow.org/ss_paper/ which was presented at the LCA
2001 in Sydney earlier this year.

It was developed by Simon Horman (horms) an Australian guy working at VA
Linux.
