If the number of customers was high, the operator would deploy native,
minial IPv6 support.  The current IPv6 usage statistics suggest
otherwise. If it the number of customers is low, I would be rather
doubtful that the number of IPv6 users would be counted e.g. in
hundreds of thousands in the first phases where tunneling from the UE
is a reasonable solution.

But in any case, whether the router is a PC or something else is
rather irrelevant; the point is that it's probably some standard ISP
industry equipment without a 3GPP "price added" tag.

Are we asking anyone to remove anything?  Is it the IETF's fault if 
someone wastes resources in a dead-end solution?  In any case, 
resources needed for a "simple" product, like the one I described, 
would be rather minimal.

(I agree that we probably don't understand the idea I proposed fully,
but because the idea itself is simple, and the method operates with
very strict premises (compared to e.g. ISATAP), I suspect it will be
relatively easy to understand it in a very short order.)
