Help Access by bluetooth headset

[HVACR257]

Hello, I am an HVACR technician and I have found the Droid to be the best PDA I have ever owned. I do however find it a little difficult to use the voice commands while using both hands or driving. I would like to know if there is any development going on to allow me to use my bluetooth headset to access all of the features on the Droid that are voice activated or is there any development of a download-able application that would allow me to do this same thing?
