The problem is building a high performance gateway. Currently you have
about the following two options:

a) set up / configure a Cisco used as 6to4 gateway
b) set up a dedicated host (Unix box) as 6to4 gateway

Approach a) is good for only few traffic, really.
Approach b) is more complex.

Both approaches aren't really appealing.

I'm waiting for vendor J to enable option c)... implementing 6to4 via
the Tunnel PIC (or other PICs including the Tunnel PIC functionalities
like Link Services PIC). It's a very simple translation/encapsulation
which doesn't require any state keeping, shouldn't be a big deal. I can
imagine a few larger IPv6 ISPs then suddenly implementing 6to4 gateways.
