Reacting to external changes
Is it possible to make a notebook react to external changes? I would like to have a notebook that shows the status of an experiment and displays some analysis, but then to update it as the dataset changes. I don't mind if I have to write some code that runs in the background and notifies the notebook that a cell needs to be re-computed.

I know that there's ui.refresh, but it would be nice to be able to do it without polling when that's possible.
We have thought about adding
contents = mo.filename('path/to/file') which will watch and refresh with updates (currently in a old branch of mine). we don't have this yet, and ui.refresh might be your best bet at the moment.
