Yes. Combine this with IP over Direct-TV, where the PC address must be
synchronized between the out-bound telephone channel (semi-permanent) and
the in-bound satellite channel (permanent). Also combine with IP mobility,
which assumes that the mobile is keeping its IP address while roaming.
Also combine with IP over CATv, where a PC at home has essentially the same
requirement as a PC at work.
All in all, at least one address per computer is a very reasonable goal,
one which we have zero reason to legislate away.
I agree with Christian completely
