A little of both seems good.  I really like the UPGRADE.BIND query, and
will have to see about getting that in the works.

I don't think we would make this sort of system tricky to implement in
an external monitoring system.  If that system knew the versions, and it
could query the public internet, then it could easily find the same data
and match the items up.
