I think what you are describing is the IPv6 ``anycast'' facility.

If you assign ns.for.customer.com with multiple A RRs these will be given to
the customer on a round robin basis.

A ``pure'' DNS solution is for you to calculate the hop counts from every
server to the customer and assign the ``closest'' server's A RR to the
customer.ns.for.customer.com

[ Of course this should mean that the primary hosting ns.for.customer.com must
be reloaded several times a day, if this is too dynamic ]
