Ah.  I forgot about the fact that recent only dealt with the source IP 
and that you could not specify source or dest in the set / update / 
check parameters to recent.  :(

*nod*  It would be very nice to be able to specify whether or not the 
given recent list is suppose to use the source or dest IP.  I wonder if 
it would be possible to add a new flag that indicates act on the 
destination IP.  That way it would be possible to default to just source 
like it currently is but still be able to specify dest when desired.  I 
suppose to make things clean it would be better to add a flag to 
indicate source and use that flag as the default when no flag is specified.
