Does anyone know how to control a projector on a pc, from another projector on another pc, in the same LAN? any solution is good for me!
actually is possible and really easy to do with zinc, wich have a nice custom object called Network.

the user can also listen (connect) to some "server" type of application that could control them remotely (even if within LAN). The similar solutions (that is based on tcp/ip protocols) could be based on Flash runtime built-in supports for sockets connection (xml socket, raw sockets) and locally installed server similar to FoxServer/ElectroServer (or any other solution including open source solution).
