Hi Bart,
I know that Michael Olsen (cc'ed) recently worked on a new approach for
implementing FOF in Faust, may be he could share his work with you? Michael?
Cheers,
Romain

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!
