network accounting by process

[Carles Pina i Estany]

Hello,

Recently I've discovered the IO Accounting (I mean, /proc/PID/io).
It's very interesting, specially together with iotop (thanks!)

I wonder: is there something in the proc fs similar for network? How
much bytes the _process_ are receiving/sending just now? I've checked
and I haven't found.

If there isn't any wat to get this information: is there any technical
problem to not have it? It looks like it would be possible to add
something similar in ipv4 level (net/ipv4/af_inet.c for example).

Thank you,
