I've helped build a new Ronald McDonald house here in Vancouver. It's one of the biggest in the world (74 rooms). As part of the design, the house has a TV broadcaster (like a hotel). It has an input so I can show an info channel around the house.
I'm looking for some software to run on a laptop that will allow for an info display. I have all the hardware figured out.
1. It would be free or company willing to donate it
2. be easy to update / design content
3. Updateable remotely via network.
My worst case is I'll use power point, but I'd like something a little more purpose built.
