Netstat -> Bandwidth per application?

[tactless]

Is it possible to get a nice table saying how much bandwidth each application is using, perhaps using netstat? I've tried doing that with iptraf, but it doesn't add up (the summary only counts the listening programs).

I made an ebuild for a program that does something like that a while ago, but it never made it into the Portage tree.
Anyway, here's the submission page for it.
