Note that some people have concerns about CARP being patent-encumbered (by Cisco) too. Unless you know for sure if something is (or isn't) encumbered, don't bother speculating about what is or isn't a problem. If you're building a product from FreeBSD usign FreeVRRPd then you should have already contact'd Cisco... It's possible that lots of parts of FreeBSD are covered by patents and we just don't really know the full situation until someone sends an infringement notice and a court makes a decision. If Micrsoft have patents over SMB (for example) then any implementation of smbfs would potentially violate that...and they are under no obligation to tell us. Picking on things because they're unmaintained is fine but speculating on patent issues is a waste of time and energy. Leave that to those soulless and lifeless laywer-vampire types. Darren
