Well I don't want to be "Mr. Negativity," but I'd like to suggest that adding this support is the wrong way to go. STF and teredo are transition mechanisms, and we're currently knee-deep (well maybe ankle-deep) in the deployment of IPv6. This is only going to pick up steam in the next few years given the impending run-out of the free /8s in the IANA pool. In my opinion we'd be much better off focusing on making our native IPv6 stack more robust rather than adding more transition protocols that will (with any kind of luck) be obsolete within the useful life of the 9.x branch. For example I seem to recall you identifying a performance penalty with the IPv6 loopback device vs. the IPv4 version.
