Really stuff so I can decideIt would be tricky, but I've heard of using javascript (not applicable with all EU's of course) to calculate the throughput (similar to various bandwidth testing pages) and set the results in a hidden field which the user would then submit in a form. Something to ponder when designing your various forms.
Of course, a better method would be to ask your visitors to provide the information by running an applet which could feed you a lot of b/w and latency information. Total capacity would be a little more difficult and various theories used to calculate it blind don't work from dialups and are questionable on broadband.
With the number of people that play with SETI and other distributed systems, I was thinking it'd be interesting to build a 'net monitor based on the same premise, pulling latency information peer to peer as well as building path maps using the multiple views. While we have this to some degree, 1M 'doze boxes would provide a lot more granular detail. Overall performance through certain paths could also be determined.
