I know. You might want to contact Andrew Gordon <arg@arg1.demon.co.uk> who
tells me for a loooong time now that the rates mechanism should be expanded
to include time based billing as in the UK.
Its very difficult to implement for me for obvious reasons, so perhaps you
can work together towards a solution for this.

1) the whole billing mechanism is partly implemented in the kernel
and partly in isdnd: it is unlikely that C++ will ever be used
in the kernel
2) as long as noone takes over the maintenance of isdn4bsd who is
fluent in all of its aspects and is able and willing to start
maintaining it with C++ code in it, there will be no C++ code
in isdnd or any other i4b utility, simply because i don't like
it. Splitting maintenance of i.e. isdnd to a different person
will not work, because the kernel and the userland utilities
are _very_ tightly coupled and this will likely lead to severe
problems.
Martin Husemann from time to time tries to inject strange macros from his
life in a parallel OO-universe into isdnd :-)) , but that made it so hard
(for me!) to understand the code after a month again and maintain it, that
i rejected and removed it because it costs too much of my time.
Don't misunderstand me please, i don't say C++ and OOD is bad, its just that
i want to make maintaining and enhancing isdnd for me as easy and quickly as
possible.
Anyway, i'll be happy to accept a time based billing enhancement to i4b
written in plain good old non-macrofied maintainable C using OO design ;-)
Guten Rutsch! (this is untranslatable german wishing everyone a nice party
into newyear :-) ! ).
