Looks like I have to brush up my MPLS knowledge ;-) I my world of MPLS 
(L3 VPNs), either packets are tagged (MPLS side) or untagged (VRF side) 
on a P/PE. Appearently, you could do a lot of other nifty things with 
MPLS which I don't grap (yet).

I think it's time to end this branch of the tread now.
