I've searched for a similar question but didn't find anything relevant. This question Closing QuickTime by Applescript is somewhat similar but doesn't address the network aspect of my question.
Specifically I would like to be able to press a "Play" button on one Mac and have Quicktime player(or similar app) start playback of a video-file simultaneously on one or more other computers on the LAN. The video files on the other computers are not necessarily identical to one another.
Latency could be an issue but I think that in situ testing could accommodate that well enough for my purposes.
More fundamentally, it doesn't have to be AppleScript/Quicktime Player. An off-the-shelf app written specially for this purpose would also be acceptable - better, maybe.
thanks in advance
