My feeling is that the chassis MIB is the incorrect spot for FRU
information.  I think the major problem is the definition of FRU
differs greatly from vendor to vendor.  I think the IETF would be
forever trying to agree on what needs to be included.

The current direction is the physical view of the chassis as it pertains
to network management and networks in general.
