Because I'm pedantic, 6to4 and 6in4 are two different things. It  
sounds like you want 6in4.
They use the same encapsulation, but 6to4 has specific magic in how  
the outer IPv4 destination is built, taken from the inner IPv6  
destination address.
6over4 is different again.

I think someone wrote a draft explaining this a while back.. not sure  
where or what it was called.
