What do you want out of it ? We have a rental system, but for anything like laptops,ipads,android devices, we have the rental system and then have a MDM over them to control them. We can track them if needed, we can push profiles (like lock down or single app use) change various settings etc, so long as connected to the internet. The best thing is that when we get a device back we factory reset it, reset it up and it looks brand new, we dont know what a client did with the device, and any data is removed. if they want to use the device like a device they can log in with their info and it looks like "their" device. It costs quite a bit to get running but does open the option of locking devices, or making set devices for shows. The annoying thing is that each "brand" has their own MDM so airwatch combines them all. They all have their own good and bad sides.
