[Thanks for the -l response, realized it moments after posting :)]

I don't want ascii logged, I want the binary data logged remotely. 
Installing tcpdump on the firewall just to log stuff is way overkill 
(though if it's there already one cares less).  I build very small 
systems (this firewall is typically <8Mb cf and ram is typically very 
tight too) and requiring tcpdump just to log pf stuff is unacceptable.

Guess I need to roll my own logger program that reads from pflog and 
dispatches to another machine.
