IPv6 only isn't a very feasible configuration right now.  Most ipv6
deployments are dual stack with both ipv6 and ipv4.   At the very
least, expect some ipv6 breakage due to a general lack of ipv6 enabled
authoritative nameservers.  If you're using a public resolver with
both ipv4 and ipv6 addresses, that might help to some degree.

I have my house ipv6 enabled right now (dual stack).  I've got an ipv6
tunnel setup on a FreeBSD box which serves out a SIXXS subnet to the
rest of my devices.  It works fairly well.

For clients support, Linux seems to work fairly well.  I did the
tunnel on FreeBSD instead due to the ease of use of pf compared to
iptables.  No special ipv6 specific rules required, and the syntax is
very nice and clean.
