Yep.  Just went through this with one organization which I hadn't realized 
at the time was a legacy IPv4 holder.  The fees were a surprise (I thought 
they'd already been paying those fees).  Needless to say, their IPv6 plans 
are on hold indefinitely.

But they're not exactly the same terms.  ARIN 'terms' for the legacy 
holder probably didn't exist at the time of their IPv4 allocation.
