Absolutely. It was one of the reasons I wanted to go for a phone like

Yes. Off the top of my head, I'd quite like my phone, when I'm at home,
notify my MythTV box when a call or text message comes in.

Yes, definitely. Not know a great deal about how the FreeRunner
software is designed at the moment probably means that I would do a lot
of re-inventing the wheel.
However, I would've thought that if every application can generate and
consume 'events', then all that is needed in your policy app is the
ability to look for combinations of events (and/or states?) and generate
new events that other apps can pick up? Is that what you were thinking.
This has the downside that all of the 'intelligence' is in an external
script/rules engine and not in the apps. That might be an 'upside'.
Alternatively, each 'rule' could be it's own script which waits on
certain events and then fires out new events that are picked up by the
other applications to do things.
Love the idea, though.
