HTC released BlueZ source code (Eclair and Froyo)

[ranwej]

As you can see, HTC released their source codes also for BlueZ http://developer.htc.com/ .
Can it help you, so you can make your program work on HTC Desire?

if the HTC Desire uses the BlueZ stack this is helpful.

However there are some devices that use other stacks, for eg. the EVO or the Incredible that use the Broadcom stack.
