My guess is if any providers were deploying it, it would be 
incumbent telco's. But one would be hard-pressed to find a 
decent incumbent, today, that hasn't already deployed an 
IP/MPLS backbone in parallel to their legacy network.

That, then, leaves you with existing operators who run both 
legacy and IP/MPLS networks, to consider MPLS-TP as a 
migration path from SDH/SONET to anything above an 
STM-64/OC-192, i.e., 40Gbps Ethernet, 100Gbps Ethernet, 
400Gbps Ethernet, 1Tbps Ethernet, e.t.c., and sub-rates 
thereof.

As pretty much all optical vendors are now incorporating 
MPLS-TP support into their devices, I posit that we are 
likely to see MPLS-TP deployments in the optical plane, as 
opposed to typical routing hardware like Cisco, Juniper, 
Brocade, ALU et al, as those (for now) do a better job at 
normal MPLS forwarding, even if they are sporting some form 
of MPLS-TP support. 

Also, it might give legacy operators more comfort and peace 
of mind to implement these "packet things" in optical 
devices than on IETF routers/switches.

Cheers,

Mark.
