MPLS for IPv6

Well, don't know about anybody else, but I've been asking vendors for
LDP6 for a while now, every time we approach them for new projects and
they always look embarrassed when they realise that they

a. don't have it

b. are not involved in the standards process (draft-manral-mpls-ldp-ipv6-02)

So please, if you are spending your hard earned cash, please ask for an
LDP6 implementation, "no demand" should not be the case.
