could you comment on christopher's observation that, given the likely

Is there any particular reason why a service over IPv6 couldn't be load balanced by putting a good number of AAAA records in the DNS?
_Eventually_, DNS packet size and a desire to avoid truncation at that level would stop you. Nothing stopping you from having say 4 As and 3 AAAAs attached to one www record though.

Personally, I think that having two AAAA records will hold you in place for long enough that vendors will catch up with decent AAAA load balancing support, unless of course you get hit by the mythical IPv6 killer app in the meantime.
