I personally think this is a *much* more desirable approach. I
contributed a small bit of code to the EITFixup for Bell ExpressVu, and
it's definitely an ugly hackish piece of work. Depending on the
flexibility of these runtime modifiable rules, it also allows people to
personalize their schedules quite easily.
Do you have some concrete examples of how you envision it working?
