With what you have, (I believe) you are out of luck. Local switching for 'any-to-any' is only supported on the ISE engines (3+) - all of which are still very expensive. Option #1 (which I know works) enable mpls end to end, and acquire an 3GE-GBIC-SC - which is the 3 port. these can be found for under 1000$ on eBay. The reason is the 1GE-GBIC is an engine1 which cannot do "Edge" mpls functionality. the 3GE-GBIC is an engine2 which can. Then, you do mpls l2transport and a xconnect. Documentation on setting this up is easily found on ciscos site. Option #2 To do anything with l2tp I believe you need a tunneling card, which requires an engine2 (backbone) card. POS-OC48 is most likely going to be the cheapest at like 500$ on eBay. I have not done this myself, nor recommend it. it wastes a slot. Option #3 do L2TP to the recently retired 7200 and do the encapsulation over IP. This I believe is your only 0$ cost option. I would check to see if all of your devices will do L2tp.
