IMO, the problem worth addressing in the IETF is the
detrimental effect of arbitrary renumbering of object
instance identifiers after a reboot.  This is a general
problem, not related to DISMAN or RMONMIB.  Perhaps
some ideas in this draft could be used to solve the
general problem.

We have a proprietary solution -- save enough info
in NV-storage (e.g., the ifName or ifAlias) to reassign
the same index values after a reboot and avoid renumbering
"returning" instances altogether. 

Optimizations to the usrHistory group should be done in
a new MIB module without impacting the existing RMON-2
conformance.

I think that all, or almost all that is being defined in this MIB module can already be performed - some features even in multiple ways - by agents that implement existing MIB modules like RMON, Events MIB, and Alarm MIB. I think that it would help the discussion if the authors could shortly describe what is the added value that this MIB module would bring, and what operations/management functions this MIB module provides that are not covered by existing MIB modules.
