Look into stateless transition mechanisms like LW4o6 or MAP. You can
push a few 10s of Gbps through a relatively modest PC with these and the
right software.
Eventually somebody will hopefully add them to the relevant router
software. Since they're stateless, most of the common "match and
manipulate" type packet pusher ASICs can presumably do it. It's not
much different than an IPv6-over-IPv4 tunnel or MPLS switching in that
respect.
