	Nagios plugin?  init-snmp()?  There's quite a leap between the two, and I have no idea how you're crossing them, but the Frankenstein experiments won't help.  The one tip I can give is to store the remote engineIDs on the client to skip the discovery phase.

	Just store and use the keys!

	I think your terminology is wrong, but if you have a cache, cache the keys.
