Our first goal here is to make the mandatory DUN aspects work.  This
means covering the mandatory AT commands specified by the Bluetooth DUN
profile, PPP server aspects and ConnMan integration.  If we have to fake
some commands to keep the clients happy, so be it.

Once we have this, we can start talking about more advanced features
you're talking about here.  Since you seem to have some experience in
this area, we'd certainly appreciate you getting involved and helping out.
