	For that subset of users which are not using IPv6-only systems.

	IMO, the real problem is knowing, a priori, precisely which set 
of servers you'd need to talk to via IPv6-only methods.  If you knew 
that, you wouldn't have to worry about whether or not there is any 
glue at the root.

	Of course, we might be able to try to answer these sorts of 
questions for small-scale testing environments, but in the general 
case it is impossible to know this.  Therefore, we have to try to 
build the systems such that we do provide the necessary links from 
the root.


	The real question is what to do in the transition period, and how 
do you decide where you are in the transition period?
