I have done some initial investigation as to how this can be implemented.
It is possible but a good amount of infrastructure needs to be put in place.
The combination of my linux-vrf project (http://linux-vrf.sf.net/) and
my mpls-linux project provide the kernel infrastructure needed.  The next
step is to make some infrastructure changes to zebra/quagga.  The first
major step is to move the MPLS LSR code into the main zebra daemon which
will require a new set of zebra protocol messages to be implemented.
Next the CLI needs to be implemented and tied to the VRF and MPLS code.
After that is all protocol interation which needs to be figured out.

I have had people show interest in helping out on this project but I have not
seen any code produced.  At some point I will switch my concentration back to
the protocol side of things (Ramon and myself have been concentrating on
re-vamping the MPLS forwarding plane implementation).

If your interesting is helping out, I can point you in the right direction.
