The DUE likely doesn't have the horsepower. I've seen the MMDVM mentioned
in passing but going to the website the code doesn't seem to be availible
or licensing.

Mobile security can be enabling, not merely restricting. Employees who
bring their own devices (BYOD) to work are irked by the imposition of MDM
restrictions. Mobile Device Manager Plus allows you to control only the
apps on BYO-devices by containerizing them, leaving personal data untouched!
