is it possible to determine how much network traffic is caused by a particular process?

Hello:

I have multiple processes running on a single Linux 2.6.x based blade
server. I am able to determine the *total* amount of network traffic
in and out on an interface by a variety of means (including the
"sysstat" utilities http://pagesperso-orange.fr/sebastien.godard/ ),
but I can not find any means of determining per process network load.

Does anyone know if this is possible by any reasonable technique? The
"sysstat" author tells me that since the kernel does not expose any
per process network counters (via /proc system or otherwise) it is not
clear how one might do this.

How hard would it be to add the capability to expose per PID network
usage information?
