Well, what I need PPP support in HAL for is monitoring a Pocket PC 
device which *is* hardware connected to a computer, but unlike anything 
else it uses PPP over USB-serial to communicate with desktop. And I 
suspect that there could be some other weird hardware that may use PPP 
to connect to a PC.

Anyway, what I'd like have in HAL is a virtual device created under a 
USB/serial/ethernet/whatever device node representing the PPP interface. 
  In the case that is most interesting to me that would be a PPP 
interface node under a USB-serial device representing my Pocket PC. A 
HAL callout could then go off and create yet another virtual device 
under that PPP interface that represents the PDA itself - in that case I 
would know that a Pocket PC device is available in the system and know 
what interface to use to work with it.

cheers,
Andrei
