BlackBerry has found another licensee for its Dolby-like licensing initiative, "Secured by BlackBerry", and expanded the venture way beyond smartphones.

From now on, licensees won't need to take BlackBerry's version of OS to earn a "Secured by BlackBerry" accreditation, and potential devices could include not just smartphones but embedded devices, so long as they conform to BlackBerry's secure manufacturing process.
