I notice two products just arriving on the market that are trying
to address these issues: [1]Cisco's Distributed Director, and [2]Genuity's
Hopscotch.

Those interested in how they've attempted to solve the problem might
find some useful information below.

The approaches, in the main, seem to revolve around 302 redirects to
the closest content, combined with utilising wide-area network protocols
to find the closest to the client.

Cisco's distributed director can also perform a similar trick but
acting as a DNS server, which I think is more interesting. I'm not 
entirely sure, but I think Genuity are selling it as a service rather
than a software/hardware product.
