Save yourself some time effort and hassle--Log to binary.  Use the ouput
tcpdump plugin and store the packets on disk in a binary form.  Once they
are there, you can come back and look at the packets in thier original
format.  That way you don't deal with the logging issues from the one
directory per IP method.

	snort -dvr <file> 'host'

That would give you all of the packets that caused an alert going to or
from  And yes, you can use any BPF filter expression you
wish.  :)
