some other approach is the way to go. It would be useful to try and
get the 'core' DIB engine architecture in first, so that any necessary
changes to the architecture can be made before too much time/effort is
spent on this.

The core should have an option to turn on the DIB engine routing, so
that it can live in the main tree without breaking existing
applications. Once the core architecture is in place, it will then be
a matter of filling in the blanks.
