Theoretically, you can use a machine of any OS platform and architecture, as long as it implements the required protocols, as a boot server or installation server.

If a number is specified for platform-title, it is treated as the menu option to boot (not a platform to match against).

At the very least, running in dual-boot mode (both BB OS and Android OS) could open the BlackBerry to a growing array of apps which it may not be able to attract to its own platform.
