Re: SSH never free

Does the GPL allow redistribution of deriviate works under
a license with a "rename if certain changes are made" clause?

If ssh had been under GPL I'd have been able to modify
the protocol it speaks and still call it ssh. Never mind
how sensible or not it would be for me to do that; it
seems that the ssh authors impose a restriction that
wouldn't be there if they'd used vanilla GPL for the
deriviate, such as a naive reading of GPL 2(b) would imply.
