As I have neither access to ISDN hardware nor infrastructure, I have no 
personal interest in the ISDN code.  However, as Bjoern has a work-in-progress 
on i4b, I'll let him respond to any questions about approach.  I believe his 
initial plan is to provide some basic subsystem code based on minimal changes 
to the current implementation.  Per my e-mail, there are no immediate plans to 
delete the current i4b code from the repository, which should make 
distributing and testing patches against i4b easier.
