	Using some tiny amount of MPLS for traffic engineering is probably 
common today.

	However, using MPLS label switching in the large scale is uncommon 
even today
in most of those operators that you mention above.  And several of 
those operators
you cite are aggressively opposed to large scale MPLS deployments due to
operational considerations (i.e. they report it is too hard to debug 
problems in a large scale MPLS deployment).

	(Nota bene: I've deliberately trimmed the set of parties copied on 
this reply.)
