Hmmm, thats interesting.  I'm wondering if its not there, but not 
compiled into my kernel?  I recall options during kernel config that
suggest they may actually be the support for this!  I gotta look into
that, thanks.

Oh yeah!  My kernel is down a bit (2.0.0, and current is like 2.0.29)
My IP_masq code being so old may be the real culprit here, but I think
you've struck gold here too about the support in the kernel itself.  I
distinctly remember the options, what I don't remember is whether the
explanation or the makefile says anything about the RFC tho'.

Cool!
