I'm planning something related, using Perl, a few modules from CPAN.
(Net::PcapUtils, NetPacket::Ethernet, NetPacket::IP, NetPacket::UDP,
NetPacket::TCP and Time::HiRes).
The Perl script grabs traffic directly from libpcap (what tcpdump uses)
and then writes it into a plain text file for further processing by a
second script.

http://www.mellon-collie.net/mycrap/grab-libpcap.txt 
for a bit of code (although you should note I'm not bothered about good
code in this - just the right answer at the end of it all).

Hope this helps.
