As Mark later reminded us, ULAs are not normally routed across customer 
boundaries.  They work great within a single network, not so great from 
ISP to customer.

In view of the fact that global IPv6 addresses are cheap and plentiful and 
are likely to remain so, the solution here is pretty obvious.
