There's a satellite ISP in the UK which does this - it's called either Hughes 
or StreamBeam, I'm not sure which is the end provider and which is the 
sub-carrier.   The equipment they provide is labelled Hughes.

As a standard account you get private (10.x.y.z) addresses on the end of the 
link, however you can ask for public-private NAT and they do SNAT/DNAT to 
your private addresses (one-to-one mapping).

I thought I'd heard that some ADSL services in UK provide private addresses 
too, but I've never had this, so I can't comment from personal experience.
