Because all the people i serve IPv6 this way are ADSL Customers, who are
allways online anyway, and like to be able to run a webserver or such.

I do /64 and /48, but any sensible subnet is possible in my oppinion.

No, i unse 1.1.3 because this is the last version which seams not to
have the sighup bug.

No

Not that many .. we have abut 5-10 Customers using IPv6

Have a IPv6 Capable router... Which is a Cisco, Linux, *BSD Router.
Probably it will also work with MacOSX or Vista doing PPP or PPPoE
depending on what service you provice.
