EFF Lists Wi-Fi-Friendly ISPs
trifster writes "It appears that *some* ISPs encourage Wi-Fi hotspots from users connections. Cnet News.com has the article here." The list itself is on the EFF's site. Most of the ISPs with policies against wireless NATing seem to turn a blind eye to it most of the time anyhow, though.
If you're in the UK, consume.net is trying to create such a registry.
In no particular order:
Wi-Fi - IEEE 802.11b compliant products
IEEE - Institute of Electrical and Electronics Engineers
EFF - Electronic Frontier Foundation, an organization dedicated to preserving online rights
NAT - Network Address Translation, typically used to provide Internet address for a local area network while using only one external IP address
ISP - Internet Service Provider, an organization who provides access to the Internet

I'd like to mention that my own provider, RCN, encourages the use of NATs to distribute home cable-modem service to all of the computers in the household. Not only that, but they even offer IP address plans if you want external IP's for the computers. RCN will help fix a problem if there is an issue with the cable modem on an internal network, and even offer a paid home-network setup option that you can add onto a free basic installation to get your home network, Wi-Fi or otherwise, up, running, and secure.
