There was the ATM-VCMUX-encaps-to-avoid-two-cell-TCP-ACKs argument,
but Henk's NLPID scheme (a truly wonderful reverse-ISO hack) is a hell
of a lot simpler.

   Not true - there are BIG security advantages to not having is-is over ip. 
   It rules
   out a huge class of spoofing attacks to which OSPF is vulnerable. Further,
   there are no evident advantages to having is-is over ip, at least not that I
   have ever heard of.
