Not offhand, but it'd be trivial to write a CGI to do this. An easy 
cheat would be to write a snort rule to log everything, run the packets 
through snort with -r, log them to mysql, and use ACID to look at them. 
This will be one-packet-per-page, though. Probably better to wrap 
tethereal with a CGI script or some-such though.

As someone already pointed out, if you want a nice GUI to look at them 
(and do advanced protocol decodes) use Ethereal (or tethereal for text 
output). Note that the display expressions in [t|e]thereal are different 
than the BPF expressions used to capture.
