Peripherals and SDK support

Quick question, I have not had time to dig into the Oculus SDK but is there support for adding third party peripherals to the proprietary communication system that links the controllers with the HMD? or would hardware developers need to setup our own Bluetooth type systems and have software developers interface with those?  How are the hardlight people tackling it? (http://www.hardlightvr.com/) This is just idle interest at this point but it would be nice to see support for a peripheral market.
