S4A Serial Comms Support

Will there be any SERIAL IO support for S4A to enable Bluetooth links etc?

I was able to operate over BT (Bluetooth) to get rid of the USB cable.
However, for exchanges with the outside world, I was forced to use the HTTP GET blocks and messaging. OK, it kind of works but very indirect and slow.

Would very much like to see a direct BT IO over serial pins or software serial, if possible.
