I can give you one example: BaneTele, a Norwegian ISP/Telco. We use
RFC 1918 addresses for internal links. None of these are visible on
the Internet - all addresses visible on traceroute etc. are normal,
valid Internet addresses.

We don't see any problems with this. We *do* see problems with ISPs
using RFC 1918 addresses for links that are visible on the Internet.
