Alex, RFC4944 and 6lowpan-hc form an adaptation layer between IPv6 and, currently, 802.15.4. To be clear: BT BR/EDR is not 802.15.4 BT LE is not 802.15.4 BT BR/EDR is not BT LE (MAC or PHY) So each MAC/PHY needs its own considerations when it comes to an adaptation layer. My feeling is that many concepts could be abstracted and maybe written in a common document but ultimately, there will be three different adaptation layers. Also "bluetooth is to 802.15.4 what wifi is to 802.11" - completely wrong comparison. Bluetooth has nothing to do with 802.15.4.
