I think that providing circuit emulation over IP or MPLS/IP networks should be simply forgotten. If ATM remains alive it is for this very application. To really provide this over IP you would need to use RSVP's int serv model what as you know never scaled to the production capacities of any service provider. With L2 transport or with L3 routing you can achive achive almost the same set of applications VoIP, videoconferecing etc, trunking what you would use circuit emulation but this is different - those new end systems and applications are desiged to work over IP networks. Old fashined devices desined to use circuit emulation are not. Also you should not be mistaken about differences of carrying ATM cell payload of AAL5 mostly used for data communication over IP/MPLS networks and trying to carry in the same way AAL1 (circuit emulation ATM adaptation layer).
