You're saying he has a patent for OpenBSD Bridging Firewall and/or Linux Netfilter functionality? Interesting to say at least. I even suspect it would cover IBM/Intel Tokenring Bridges as well. Then again I'm not a lawyer luckily and/or on your end of the table. If he wants to sell it as an appliance without source code, then OpenBSD may be a better path to follow due to the nature of the BSD and GPL licenses. Otherwise he/you may go the path of D-Link/AVM/SUN when SFLC finds out what your client is doing. You may want to get some legal advise and SFLC is in most cases willing to answer your questions btw.
