Tracks some of these metrics. There are likely programs that do the same.
I'm interested in what program on my computer is talking to who's server and for what purpose. Somewhere I read that a guy with a fresh install of Vista found his computer talking to a homeland security server. I'd like to know what software he used to do that. I'd like to shut down all the bandwidh sucking chatter so only the programs that do something useful for me are the ones talking.
Download-/Upload-o-meter - does it exist?...
I've gotta imagine there'd be some way to figure out your internet usage metrics, right? Do anti-virus programs keep track of this?
