I have a multi-building setting where they want digital signage. For now, 6 small monitors in one building, 2 in another building, and 1 or 2 in a third. Each set of signs in each building will be the same for that building (3 different signs being shown). More buildings and signs will be added to the system later. The current three buildings all are connected with cat and coax. The person updating and changing signs is in another building and wants to make all updates from his office.

Does anyone have experience with a signage system that would fit this setting? One option I did consider, if it would help the price, if I could find a signage system to generate the signals and use the Ethereal MB3 system to distribute to the panels.
