<br><font size=2 color=blue face="Arial">One of the most immediate applications
of WBMM, for which no standard capability now exists,
is in remote monitoring. In general, any set operation (and many
get operations) must be disallowed for enterprise security and confidentiality
purposes. If one is producing proxy devices to support such
a capability (as NetSilicon is), it would be absurd to require
support of operations that could never be used. Now, it is
not clear how important full compliance to a PWG
spec is, but if compliance requires supporting a whole
set of unusable operations, it will become meaningless.</font>
<br><font size=3> </font>
<br><font size=2 color=blue face="Arial">I also have suggested partitioning
this effort, although not along the same lines. I think we
should encourage more discussion on this, particularly on who
plans to apply what part of this capability first rather
than what appears easier to do first. Indeed, since prototypes are
a necessary part of the standard development, I think
getting volunteers to apply these ideas may be the determining factor
in the "subsetting" definition and order.</font>

Ouch! disallow SETs? </font><font size=3><br>

I agree (propose) with the concept of subsetting. I am thinking more along
the lines of a "growth path"... where we start with Extranet
as target and possibly limit our scope to devices, then move to include
Intranet and also expand to services, then, finally include queues</font><font size=3>
<br>
</font><font size=2 face="sans-serif"><br>
But I think SET capability is needed, even at the lowest compliance level.
If not, how, for example, would a remote manager take a device off-line
should this be necessary... or post a message to the opPanel?</font><font size=3>

Harry had brought up the notion of different classes of compliance
in his last minutes. I think this is as it must go. For WBMM monitoring
applications, any set operation let alone queue management
must be disallowed. But that does not mean that we ought not identify and
format set operations.<br>

I do think doing some sub-setting makes sense - in the case of queues,
not<br>
all devices/services managed by WBMM will have queues to manage. <br>
<br>
Once we understand the potential subsets, we can talk about which ones
need<br>
to be in WBMM 1.0, and which can follow (or potentially be done in parallel.<br>
