In IPv6, you can run BGP/IPSEC. Works today.
Bullet 2: Not sure how you'd do that, but, since the "client side" can't control what the upstream side accepts, I'm not sure why that matters. Bullet 3: You have the option of doing that in BGP today, but, I don't know of any versions of BGP that are so limited other than by memory constraints. > I think a evolved version of ebgp multihop is workable, but you'd still need > some lightweight form of hooking back into the BGP table. > Not sure what you mean by this. Pretty simple, really... ISP advertises default and accepts <CUST> prefixes with a simple prefix filter. <CUST> accepts default and advertises own prefixes. Done. Works today.
