No problem,  everyone tunnels v4 in v4 and the "outer" ip address is
your 32-bit ASN and you get an entire /0 of "legacy" ip space inside
your ASN.  Just need to get rid of BGP and go to some sort of label
switching with the border routers having an ASN to upstream label table
and there ya go. Oh, and probably create an AA RR in DNS that is in
ASN:x.x.x.x format.  Increase the MTU a little and whammo!  There ya go!
