Have you thought about making something like this a startup? A SaaS metrics dashboard service? I deal with a lot of call centers and marketing houses that do big "competitive" dashboards to motivate/track staff and they have to roll their own systems. I'm sure a bunch of tech groups would like to have a Panic-esqe dashboard, but wouldn't want to go through the hassle of doing it themselves. Not sure if it is a huge market, but could be interesting!
Hardware + per customer customization + sales cycle which requires talking to people = I have no interest in that business at all. But if you want it, go for it.
It wouldn't necessarily have to involve any of these. Most of these that I've seen have been cobbled together through Excel, so they have the skills to get everything into Excel. You could offer a product that made really pretty charts around these metrics.
The hardware would be just a 720p TV which they would have to buy and mount - you would just sell teh software.
What companies? I did a search for "LCD Marketing Dashboard" and didn't come up with anything. Not doubting you, just curious what these would be called!
