Vista - Vista (& Now Win 7) Bluetooth Stack Questions

The emasculated Vista Bluetooth stack has been the subject of ongoing debate since Vista's inception, and now it continues with Windows 7. (I multi-boot and I see the same issues in both OS's). The question has always been, why did Microsoft castrate their own stack and make it so difficult to use 2 different stacks simultaneously?

It worked fine in XP where I actually had 3 Bluetooth dongles all up and running....!

I'm using the Microsoft Wireless Entertainment Keyboard & Mouse which use a v3.0 transceiver. It works fine if it's the only receiver.

My new PC also has a 28-in-1 media card reader w/Bluetooth (v2.0) in the 3rd optical drive bay, and I have to disable its driver or Microsoft gets all upset and wont come out and play. The reader uses Broadcomm drivers.

Has anyone got suggestions on this dilemma? If I can get them both to work together in Vista then I can do it in Windows 7...I hope.
