Bluetooth capable? Built in? Way beyond state of art for systems application. Surely not. Way too provenient. 
Well, you dashed my dreams on the rocks of reality...
Webikeworld will likely have their hands on one of these very soon and give a full review...they do really good reviews on helmets, IMO.
Off topic a bit, but interesting information from the webikeworld page on helmets:
The Motorcycle Rider Conspicuity and Crash Related Injury study conducted over 3 years in New Zealand (1993-1996) found that:
Motorcycle crash-related injuries occurred mostly in urban areas with a 50 km/h speed limit (66%).
Most crashes occurred during the day (63%) and in good weather (72%).
Riders wearing reflective or fluorescent clothing had a 37% lower risk than other riders.
Compared with wearing a black helmet, use of a white helmet was associated with a 24% lower risk.
Self reported light colored helmet versus dark colored helmet was associated with a 19% lower risk.
75% of motorcycle riders had their headlight turned on during the day, and this was associated with a 27% lower risk.
No association occurred between risk and the frontal color of riders' clothing or motorcycle color.
The risks are 33% for wearing no reflective or fluorescent clothing, 18% for a non-white helmet, 11% for a dark colored helmet, and 7% for no daytime headlight operation.
Conclusions: Low conspicuity may increase the risk of motorcycle crash related injury. Increasing the use of reflective or fluorescent clothing, white or light colored helmets, and daytime headlights are simple, cheap interventions that could considerably reduce motorcycle crash related injury and death.
