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.

Yes there are some sites that are IPv6 only. You can get some info on
www.sixxs.net

AFAIK, unless changed recently Cisco keep dragging feets and their
routers are *much* slower when dealing with IPv6, other vendors seem to
do better. But I have not looked in the area for a couple of years, so,
maybe, Cisco has released something better now. (Afaik this was also one
of the reason ISPs refrained to deploy IPv6 back then as the network
performances were definitely affected).

Simo.
