What exactly are you trying to do with MPLS?  PFC3 will support most  
things without additional modules (OSM,SIP) with the most notable  
exception being local switching.   You can get around that by looping  
in and out of the box if you need to.  No VPLS as well, but I'm not  
too keen on running VPLS anyways. :)  There are some restrictions with  
regards to when MPLS packets are recirculated that you may want to  
look into.
