Preferred DFU / USB field update

I'm thinking seriously about migrating an application to RT. I need to offer users and developers a field update method for firmware binaries. What is the recommended method for DFU? On other temporary MCUs there is a bootloader which is able to receive a new image and program it into flash. The image copy typically operates over USB HID so that no driver installation is needed, only a Host-side executable or script. 


Is something like this available for the RT series?


I consider making a development board for the project partners. The current version uses USB DFU, and I would prefer that method for both development and field upgrades later. That way we move away from dev kit and toward the end product at an early stage in development, which I believe is good.


Best regards,
