So they can use addresses from the probabilistically unique range under the space fd00::/8. There is, in terms of raw usage, no difference between using fd00::/8 or fec0::/10. External networks would still have to route the prefixes back to you for you to be reachable, which is just as hard/easy under either system. > 2.

No, the registered address space is under fc00::/8. The two spaces are distinct, as per section 3.2 of http://www.ietf.org/internet-drafts/draft-ietf-ipv6-unique-local-addr-01.txt It'll be many, many years before additional space needs to be allocated for these local address types. > So between the 2, I do not see a solution that will work better than a > RFC1918 type of address space.

Well, addresses under fd00::/8 and fd00::/8 can be used locally just like site-local addresses, only they have the nice property of significantly reduced (probabilisticly unique) or complete removal of (registered unique) ambiguity, so I don't see where your concern is? It is not unlikely that people will be lazy and just use fd00::/48 for sites, and thus add back in great ambiguity to the probabilisticly unique address space.
