Interesting. KC is offering firmware and update tool. The module receives raw HID frame and seems to meet our requirement but document is a tad scarce.
As for pricing RN-42 is fairly cheap, I think.
Roving is a subsidiary of Microchip now and we can get it for $15.27 or less from their DIRECT shop.

Yup, for small quantities the RN-42 seems to be the cheapest option until so far.
I've been looking for some other alternatives but no success.
Tried the BT 43:

Hi Woody,
Many thanks for giving us the chance to propose our Bluetooth solutions for your project needs.
We're a wireless module manufacturer with wifi and BT solutions and we also write and maintain our own BT certified stack.
We also sell the BT-243 USB stick which is a very good way to quickly evaluate the functionality of the modules.
It's very quick, simple and convenient to just plug the USB stick into a PC's USB port and run something like Windows HyperTerminal then start to send it AT commands.
No need to solder up wires to a bare module before you can start testing
Regarding your request for pricing:
Modules 10-24 25-49 50-99 100-499 500-1k
BT43-LT $16.55 $15.45 $14.15 $12.75 $11.70
Please include your FedEx/UPS/TNT/DHL/other carrier account number to cover the shipping cost.

I've tried to contact Blue Packet to see the prices of the BPM730 module however nobody there seems to care about small sales quantities ...
My dream is to get the firmware source code to update the CSR HC-06 module into one HID enabled module (I bet it was what the Bluefruit EZ-Key guys did)
I saw a few vendors at alibaba but most of then are selling the CSR HC-06 saying it is HID enabled (by the pictures I saw) and I'm kinda afraid of fake or modules without HID
