I do like the idea (but)... if the 'S' in STEP means simple to deploy
then couldn't you achieve the same by just using L2TP? the user runs
the LAC the ISP the LNS. IPv6/PPP/L2TP/UDP tunnelling between
them. the ISP would typically have the required infrastructure
already. authentication is defined and it should do NAT traversal.
