I agree the argument is well laid out, and would be interested in 
hearing the thinking of ISMS in response.

I'm more than a bit concerned, however, when folks start talking 
about solutions that will permit things to pass through firewalls 
without configuration. Those in charge of firewalls are often 
purposely setting policy. If there is a perceived need for a policy 
that prevents SNMP traffic, then it should remain possible for the 
administrator of that network element to make that call. I must say I 
have some concern with overlaying SNMP on SSH, since that precludes 
the firewall knowing whether the traffic is general SSH keyboard 
traffic or network management.

Let's hear more about the thinking involved.
