Something seldom discussed in this context is the presumed absolute need for the telecom
service provider to have all connected devices adhering to their own low-level hardware
protocols, and I guess to protect access security.  I imagine it would be disastrous to have
bit jockey's fiddling with low-level protocols if this could endanger the network.

Despite my love of open systems, I could live with this part of the system in binary if the
rest was open.  If there was a published API for this binary blob on making calls etc would
that meet most needs?  Would it need to be a kernel under the kernel?

My very limited understanding is that the phone is a separate system from the UI/peripheral
devices, and that the communication takes place with a well-defined protocol (for some
definition of "well-defined").

I could be totally wrong, though at the very least, I know that they don't share the same
memory, as that would be insanity.
