Yesterday Meraki updated their MDM system to release a BETA version of their Device Enrollment Program (DEP). This means you can now have your iPads auto enrolled over the air (wifi) into the Meraki MDM System Manager and the profile can not be removed. However unfortunately this is only available in the US at the moment and only if the devices are purchased directly from Apple in bulk. But still it’s a start to what could be a really useful tool.
