IP packet manipulation within Erlang

How suitable is Erlang for a small project where I'd like to

- grab all incoming IP packets
- perform some IP header manipulation
- send out the modified packets

I'm aware I need some kind of bpf/pcap driver to get the packets into Erlang (or 
does Erlang now have something in this front).

Do you guys have any idea how fast this whole thing would be compared to doing 
same in normal userland C program? Or even compared to doing the manipulation 
within Linux kernel.
