How do you manage your ArcGIS floating license pool?
I have to field several calls a week, or sometimes a day, from staff wanting to be able to check out Spatial Analyst or ArcInfo but they can't because there are none available. I've a little script I run to get a list of who's got what, and then need to either make phone calls to find out if Sam or Ellen really is still using SA or pass on the list of names to the caller so they can do the leg work. Better than half the time the user has simply forgotten to downgrade their license level, or close ArcMap/Catalog after they've done what they needed to do.
This is monkey work that really should be handled by a computer. I've not found anything that really works for us yet. What do you do?
