When Amazon introduced its Kindle Whispercast service back in October, it did so with the promise that '"bulk app distribution" would be coming soon for Fire tablets. Fast forward to today and that feature is now live, giving organizations the ability to push purchased applications from an administration account to all managed Kindle Fire tablets. Yes, that even includes BYOD devices, although those users will have to accept an opt-in prompt to participate. If your school or business already participates in the service, there's no need to take any further action -- the ability should be enabled right now. But if you'd still like to sign-up, you can do so at the source.
