We've been talking about specs for the next generation of our sites, and one of the things that would be really helpful is to know what sort of net connection (or more precisely, the speed of the connection) each of our customers has.

I was thinking perhaps there's some little script somewhere that exists that we can install server side that will monitor how long it takes for a given user to download a particular video, and write that info to a table.

I checked with NatNet, but they didn't have any suggestions. Has anyone else heard of anything that would do this, or have any idea how to write a script to do that?
