Saverio and Sandra already had a look at the DISMAN-TRACEROUTE-MIB.

As editor of draft-ietf-disman-remops-mib-v2-06.txt I wonder
what you consider as 'perceived deficiencies with the RemOps MIB'.

In the context of IPPM, there is certainly the deficiency, that
you can only store measurements that were performed locally and that
the tables for storing measurement results are read-only.

But anyway, does the IPPM WG plan to store traceroute results in a MIB?

Thanks,
