Thanks for all the great replies!!
Morgan: that is checking for terminated instances in AWS, but they may
completely vanish from AWS (not even shows as 'terminated' anymore)
and not necessarily get processed, unless the script is run often?
Cassiano: very cool about knife not having to be setup.
Thom: SNS , SQS, looks like the way to go
Alex: Nuvole has an implementation for that
Brian: has an implementation for Nuvole
each step further it seems... will look into these suggestions.
