Good to see someone else thinks this might be useful. :)

There are some very small non-libpcap Linux sniffers on the Packestorm
site that don't have nearly the features of tcpdump (mainly because they
were designed to only snatch passwords). 

I don't know how important portability is to busybox. There is also a
small LBL sniffer called pcapture that only saves the files (vs. decoding
packets) and doing something with the ethertap device or Linux Socket
Filter might be worth looking into. Of course it all depends on what would
be a minimal feature-set/maximum size that folks could agree on.

I went ahead and created a sourceforge mailing list
trinux-usniff at lists.sourceforge.net if anyone else wants to discuss this
further. There should also be some links to mailman from the trinux site
to subscribe to it although the old-fashioned way works as well.
