no - the ptomaine effort attempts to say that lets continue to use the 
inter-domain routing protocol as connectivity + policy + TE and lets work 
how to identify the 'noise' associated with policy + TE and limit its 
promulgation with the routing fabric to some loosely defined boundary.

This strikes me as a stop gap rather than an enduring scaleable solution, 
in my humble opinion. I dont mean to devalue ptomaine as I think that 
buying time is good if you have a problem, but my cautionary note is along 
the lines of not mistaking the band aid for the cure. :-)
