Can software under the BSD license be forked into a GPL version?  Basically I am wondering if the firewall code that the OpenBSD guys are developing "PF" could be ported over to Linux?  

Hopefully PF will be as good as IPfilter.  IPfilter is on every *NIX except Linux because the developer hates the GPL. 

Netfilter/IPtables is powerful, but so complex that it is almost unsable in a simple enviorment, nevermind a complex enviorment with multiple networks and special access to certain systems.  IPfilter is pretty simple to use and very straightforward and PF is suposed to use the exact same syntax.
