Seems pretty far fetched to me that there would have ever been a chance to have IPv6 in Win9x. For comparison, afain FreeBSD was the forerunner with IPv6 support, and they got it in 2000. So I'd say they "missed the deadline" by 5+ years. It was probably around 2005 when we realistically had somewhat usable IPv6 support at base OS level.

I think the point was that it changed the whole demand curve. If the major consumer OS at the time had v6 support things like FreeBSD would have added it earlier.
