turns out that the software I mentioned (virtmodem from 1995) does  
indeed use a pty pair. Although I've not had time during the week to  
get it running again, I suspect it would probably work on a recent  
kernel/pppd.

Is the line discipline so much of an issue when using ppp connected to  
a fake tty? could that not be handed on the proxy side inside ofono?
