I personally don't agree with your thoughts.  BGP - yes it scales well, but
for signalling??  So a signalling packet hits the RR which then reflects
that signal to each end point??  That's slightly silly in my mind and I
believe LDP will actually win in the long wrong.  Also I believe that the
RFC/IETF bods are nearly edging towards LDP as the signalling protocol for
vpls and such and in that instance the companies who have been arguing over
BGP being better than LDP will have to rethink their strategy.
