I do see this in my BGP4+ routing-table:
*> 2002::/16       3FFE:608:2:2::10     0   2611 3257 4697 1251 109 i

Well, it should be an ideal situation, wouldn't it?

For people who only have 6bone, they will be directed (using the BGP-4+
information) to the 'closest' gateway, so they do not have to cross half
the planet to a 'universal' 6bone-6to4 gateway.

For people who only have both BGP4+ and 2002, the system automatically
chooses the best way.

Cheerio! Kr. Bonne.
