A good demo routine?

I'm running trixbox for my business. I also want people to be able to demo the system to get an idea of it's capabilities. Ie. press 1 to talk to someone, press 2 for a demo.

Does anyone have a good routine to set up or maybe some sort of demo script? Maybe in combination with something they could watch online so they could see the menu's, see FOP and listen in on a conference call at the same time. This would all be automated ideally or maybe I'm just dreaming.
