ever.

tunneling may be good for a very tentative experiment.  and it can
be politically useful.  but for anything production-like, it simply
does not have anything like the reliability and scale needed for
real use by folk just wanting their packets to be delivered.

i hope not, as it just can't technically and operationally do so.

to learn the difference between a router as a forwarding engine,
and a router as a tcp stack, just run a tcp stack tester against 
a cisco on a local lan.  and this is why multi-hop ebgp sessions
break so easily.
