I wish Microsoft would include support for IPV6 in the PPPoE interface on windows xp.  That would give me an easy way to provide ipv6 connectivity to my customers.   I understand that Vista is supposed to have that by default, but that doesnt't do me much good as 99.9% of my customers have older computers. Oh, and While you're at it,  why not upgrade ICS to support v6 routing. that way I dont have to wait for soho hardware vendors to make an ipv6 capable router.
