Like the categories they use to show a headphone, keyboard or mouse icon next to a device in the Bluetooth menu?

[freedomben]

yes, but with some method for programmatically reading the icon so they can know what type it is

Machine learning would make that task fairly trivial. Much like the TV show Silicon Valley, but instead of "not hotdog", "not headphone" and then treat it like a keyboard.
