Transparent Bridging and Firewalling pf out rules

[Jason Hammerschmidt <Jason.Hammerschmidt@maclaren.com>]

Does the bridging environment out filter rule constraint still exist in 
OpenBSD 3.0?  The one that states a " pass/block 
out" has no effect, therefore you have to use a "pass/block in" on the 
opposite interface if building a transparent firewall.  This is taken 
from old documentation, I'm assuming the old  2.9 ipf days.

In short, can I build a transparent (read bridge) firewall using pf and 
include pass/block out rules?
