I am adding a second projector for a special event (and possibly permanently). Driving both projectors from a common source using a signal splitter and cabling is not possible given the sanctuary design. My only option is to run two instances of OpenLP on separate hosts (both Raspberry Pis).
Does anyone have recommendations for synchronizing the two instances? My initial thoughts were to try network keyboard sharing or remote control via some sort of TCP packet replication (I don't even know if OpenLP's protocols would allow for the latter). I presently control OpenLP, running on a Pi, remotely from an Android tablet, but I am open to suggestions.
