Indeed! RFC1918 addresses work fine for me on my LAN at home and this 
week I will be connecting a corporate LAN also using RFC1918 addresses
behind a single static IP address. In both cases I am using a FreeBSD box 
with proxies like CERN httpd and TIS Firewall Toolkit to transfer the 
traffic rather than a full-blown NAT. 

More ISP's should be doing this IMHO.

Then why have they not yet come up with a workable policy like the one 
RIPE uses to release /16 blocks incrementally to new ISP's?

Basically, the market demand is INCREDIBLY HIGH and businesses want to 
build up infrastructure to meet this demand but the Internic IP address 
allocation procedures are too confusing and take too long.

I wonder if the main problem isn't simply that not enough people know how 
to have an impact on Internet policy as expressed in the RFC's. A heck of 
a lot of people starting ISP's have backgrounds in business, LAN's and BBS 
operation but they just don't know how the Internet works or where they 
can comment on Internet policy. *sigh*

Those squeals disappeared darn fast!
