I'm sure we could do something similar, if we could get access to a 
similar set of targets in exchange.

It would probably be nice to have some sort of moderated machine-readable 
list of targets, with geographical locations, and a simple bit of code to 
pick a "random" set of hosts to sample, such that you can build up a 
profile of network performance to geographic areas of the internet 
(transfer rate, hop count, RTT, packet loss).

I'm fairly sure there's commercial services which offer this, but it 
wouldn't be too difficult to build a freeware solution.

Sure, if this turns into something we can all gain something from, we'll 
be interested, and will probably put up a box to support it.
