General :: Bluetooth Reverse Tethering To Windows 7 PC?

How can I reverse tether my Android phones to my PC via Bluetooth? Is this even possible?

PC is running Windows 7 x64. Phone is an HTC HD2 running JellyBean AOSP from NAND. I know Wifi would be easiest, but this is a work PC and company policy is we are not allowed to run our own Wifi networks.

I managed to connect the HD2 to the PC via Bluetooth with a PAN network, it only worked when I turned on Internet Tethering on the phone. this makes the HD2 into the server and PC into the client so PC can use phone's internet connection. I need the reverse! I need HD2 to be the client, PC to be the server. I found a Bluetooth PAN client from the Play store, but it can't connect via PAN to the PC. I assume because the MS BT stack only has a PAN client and not server. Is there such a thing as a PAN server for PC? I've looked at Widcomm and Bluesoleil BT stacks, but neither specifically mentions having a PAN server.

I found this tutorial that sounds promising, using DUN instead of PAN: URL....It's for reverse tethering an Android device to another Android device. Looks like BlueVPN on the Android side will do what I want, be a DUN client. However, similar problem to PAN, I can't find a DUN server. It's apparently not built into the MS BT stack either.

Is it even possible to reverse tether an Android phone to PC over Bluetooth? Only other idea I can think of is to use an intermediate device as a bridge. USB reverse tether a phone to PC, and use phone's Bluetooth tethering abilities to tether my bluetooth phone to it.
