Personally, I'm rather hoping on some kind of OS virtualization
scheme allowing you to run parallel (but isolated) policies
in the same unit using a stock version of the mobile OS.

There are other sectors that have similar needs but cannot afford
specific devices or OS reflashing such as health-care, banks
and the police.

With the advances in HW this is at least not technically impossible.
VMWare has already show-cased their take on this matter.
