         No. Don't misinterpret what I am saying. I think that YOUR approach
will significantly increase the cost of a device.  There are other approaches
that leverage existing technologies that are already implemented. I think
the cost increase for these approaches is marginal in comparison.

         You are basically trying to meld ATM OAM technology
onto MPLS, which isn't an easy thing to do nor is it a good fit, IMHO.

         A solution to that can be implemented in one's lifetime and will not
significantly increase the cost of the device on which it is implemented.
Such solutions generally do not require a complete re-design
of all hardware that is deployed in the world and that generally seem
to work pretty well at this point.
