Basically, think of the GPL's requirements for what must be distributed
if you were distributing the server the user interacts with.  This would
normally be "the server and everything you link with it".

Hmmm, good point.  That goes back to the problem regarding Debian not
keeping old versions around.  I had imagined that the user could usually
just point to their distributor unless they personally changed the
software, but that doesn't cover the case when that distributor no
longer distributes.
