What most networks do is just police/shape traffic at 
whatever rate you can afford to pay for, as it enters/leaves 
the provider's network.

As MPLS is in UDP, all the provider sees is IP, as they 
should. I don't think there will be any "special treatment" 
to UDP traffic carrying MPLS, vs. UDP traffic carrying other 
payloads.
