now that you bring it up, we made a program that would do something like that but with a different approach.

it was certral location with many redundunt location that would be queried under various conditions and when query was successful the first thing that would be done was to update the "backup central locations list" and then do the rest of the work.

in case you are wondering what this program did: it was a windows auto update ancestor on a very large network that worked like a charm.
