The only difference between the Remote Encryption Management Image flow and the ISV PBA flow, which incorporates the ATA-Over-LAN Bridge, is that the PBA environment is a host based execution environment rather than the Remote Encryption Management Image.  This means that the step to launch the Remote Encryption Management Image can be skipped since the PBA will be the default environment that loads when the machine is powered up.

The complex part about ISV PBA integration will be the implementation of the ATA-Over-LAN Bridge in the PBA.  Unless the PBA environment is a similar Linux implementation to the Remote Encryption Management Image, it may require a port of the ATA-Over-LAN Bridge.  It is known that PBAs are implemented in a wide range of operating systems ranging from DOS to RTOS, etc.
