We're planning on redoing the kernel-userspace interface and in the long run the traditional raw HCI access wont exist anymore in userspace. In order to accommodate both old and new kernels in a clean way the interface towards the kernel needs to be easily interchangable, which is what hciops is trying to do (it's just a first step in that direction though). One of the drivers for this change is the need to have the security logic in one place instead of it being split between kernel and userspace (this has caused all sorts of trouble with SSP for us). Originally the plan for the new kernel interface was netlink but now the idea is to simply extend the stack internal messages of raw HCI sockets with a more complete two-way protocol between the kernel and userspace. You should (hopefully) be seeing more patches for this still during this year.
