Same thoughts here.

Like to know how many MPLS deployments are there that do QoS??!!

This is very reminiscent of IPv6 - a lot of talk from IETF and the
developers and we were on the verge of recommending to a large customer
that they deploy IPv6 but then backed out.  We could find only a few -
if any - decent deployments out there.

There has to be more to MPLS deployment than TE in the core of the
networks where such folks as Nortel engineers to Dr. Jain will tell you
that the optics is moving into circuit (read wavelength) switching in
the core. 

Like to hear some coherent, engineering thoughts.
