MDM solution for free worth looking at!!
I have been playing around with Meraki's free MDM solution which has ticked a lot of boxes for me. I even phoned them up to confirm that this was free to use! But this is a free cloud based MDM solution for iOS, Mac, Windows and android soon.
It allows you setup profiles and using push notification send profiles and updates and also APPS :)

Well worth a look if you have iPads or iPod Touches and iPhones.
