This would be a great feature. We have an old asset management app that we are looking to replace because of its buggy behaviour. Hence the LanSweeper trial I'm looking at. But one the the features that keeps it around is it lets us use a map of the office and actually place assets on it.
A quick example would be once LanSweeper discovers a user/printer/device have the abilit to place that user on a floor plan. That makes it easy to know where to go to find something.
