Anyone using digital white boards?

I want to put a digital white board in our 5 production rooms and 1 in the warehouse. All 6 served up from a centralized source from the production managers office.

Essentially I need our production manager to be able to access and update each white board in real time to create and change production schedules for each team.

A search produces many results, often with little to no support from China and India based companies who only repond via Skype. If you know me, I want US support and a person live on the phone during normal hours.

Thanks for any input you can provide.
