Most MPLS networks use a combination of point to point, frame and ATM facilities as the infrastructure. The phone companies use ATM just about everywhere to deliver voice across their networks. I don't see ATM/FR equipment being EOL'd anytime in the near future.
really, that is interesting.

Unfortunately, I don't think it was ever fully utilized.. From what I understand, MPLS takes some of the good bits and combines it with traditional routing.. But I don't see a lot of MPLS implementations either...look to the private networks luke... Seriously, many large private ATM/Frame networks are transitioning to MPLS networks because the ATM or Frame gear is/was/will-be-shortly EOL/EOS from the vendors. The costs to run these networks don't jibe well with the alternatives. Now, start the discussion on: "private network" and "mpls vpn" and "oops, hey, that runs over the same routers as that bad-old Internet thing with the haxors and such!" :)
