My interpretation of the question was whether the gateway would support tunnels running over IPv6 to carry 44/8 traffic. That way, endpoints on DS-Lite, for instance, could tunnel their 44/8 traffic over IPv6, and those of us with dual stack might be able to avoid the usual issues with routers that don't support IPIP encap packets over NAT properly.
I'm not sure amprgw is the place to do that. The IPIP tunnel network is a mesh, and such endpoints would not be able to participate in the mesh.
On the other hand, local gateways could offer this service to local users, when they are both on IPv4 (to participate in the mesh) and IPv6 (to service local users).
E.g. we offer connectivity to local users on our gw-44-137 using various different protocols (all over IPv4): - IPsec tunnel - GRE (with or without IPsec) - L2TP/IPsec - OpenVPN
Some IPv4-over-IPv6 protocol(s) could be added to that when the need arises. However, all ISPs offering IPv6 locally that I know of, offer dual-stack. There have been some requests to offer IPv6 inside our hamnet, but we are not quite ready for that yet (depending on support in routers etc). However, I never received a request to setup a tunnel over IPv6.

Good point, forgot about the mesh bit.

That would work, and I could implement something and test it, if I moved the endpoint of my existing allocation to my VPS (which is close in network terms), and completed the last hop to here via IPv6. Having access to decent broadband now opens up options I wouldn't have considered previously.

Might be something to play with.
