You would more likely acheive your goal with Snort rather than tcpdump.

Snort has the ability to inspect packet payloads, in addition to layers 
2/3/4. It may take some fiddling, but it should be possible.

Snort can output into tcpdump format, so the end result should be what 
you'd expect.

The problem with snort is that, to the best of my knowledge, it has no
'ignore p2p traffic ' option.  It also seems like it might be a little
slow for what I want.

I'll look into that though, just in case it already does what I'm
looking for.

Any suggestions would be appreciated.  Thanks.

-Peter
