Afaik nothing specific to wireless, one GOOD thing is that you have a
full public address, and you can have a public address on each machine
in your home/small shop/whatever and get rid of NAT and all the problems
it causes.

Kind of like NAT, then. Is there an IPv6 address registry? Can I acquire
a publiv IPv6 address space (even if it isn't routeable right now)? I'm
assuming that IPv6 isn't being routed right now and most people just
tunnel. (I'll have to ask my ISP).

No tunnels here...
And firefox uses ipv6 automatically if I browse that site.
The normal registies are maintaining it:

% This is the RIPE Whois query server #2.
% The objects are in RPSL format.

(...)
% Information related to '2001:840::/32'
