Interesting.  We're interested in Wes's proposal precisely because we
believe that it will be implementable with changes only to the SNMP agent.
The agent will have to work at it a bit, but isn't this the scenario:

  - PDU: "Get columns { 4,5,6 } from table foo for those entries where the
value in column 8 = 300"
  - Agent to subagent or instrumentation: For each row i , Get (foo.4.i,
foo.5.i, foo.6.i, foo.8.i)

Then the agent looks at the column 8 values it retrieves, to decide which
rows to use and which ones to discard.

If this is the way it works, I don't see how the subagent/instrumentation
is affected at all, or even knows that anything has changed.
