The microchip RN4020 bluetooth module is still not released, and the latest news is that it will be available Sept. 25th.
The module has an embedded bluetooth stack and can be controlled either from an external micro with rs232 serial, or by internal scripting.
Here's the only document I could find that shows anything about the scripting. The setup commands are well documented, but only brief mention of the scripting. I'm sure more app notes are being written now.

And the datasheet, that doesn't mention scripting at all.

Digikey has created a slot for the product ($10.60), but no stock till september...

The module has scriptable i/o pins and adc inputs, and can be programmed through the loading of scripts via the rs232 port. Sounds interesting.
