The mroe I think about it, BGP would be a pretty snazzy way to do 
this... although something bothers me about using BGP as an IGP.... but 
it obviously scales well, and it can be controlled tightly.... I can't 
think of any reason why it wouldn't work, other than it is probably 
significantly slower to reconverge in the event of a failure unless I 
start munging up the hold timers...
