Quite a few large ISPs use these types of addresses. While @Home may
sometimes be the idiots they appear to be, they have effectively used
10.0.0.0 network addresses. As long as the ISP entry and exit points know
who's who and where to point routes, it works for transit and stub networks
and saves address space. It is actually a good way to keep bogus traffic
from hitting the net, it becomes locally routed in that ISPs AS. You can
filter rfc1918 addresses to a black hole route or route them somewhere
local. Quite often smaller ISPs do not filter these and force excess
network traffic to the upstream providers (albeit small amounts).

Oh dear.. rfc1918 address space visible? I hope its just a piece of
network kit that uses its management lan as the reply to for ICMP
I know that solaris boxes, when routing between qfe ports will reply to
traceroutes going across them with the IP from the hme card. Not that
you would want to do any routing with solaris machines, ever.
