Hi there, imagine a medium sized office room, where four engineers hack away (all of them currently have Fedora 22 workstations, to stay on topic.) On that room there's a fifth PC, hooked to a big TV on the wall (also running F22) that has Firefox running full screen with some visualization of sorts (dashboard thingy). Those five computers are all on the company wired network... nothing you haven't seen a thousand times before. Now, Sally, one of the engineers wants to share her desktop with the others and uses application XYZ to project/cast/extend/send it to the big TV (via its PC, of course). All of them discuss whatever was on her mind, and five minutes later, she closes application XYZ and the office goes back as it was before. Fred wants to do the same, and he does. Actually all of them can. They asked me what is XYZ. I was thinking on a member of the VNC family, but what they want to do is the reverse of what one normally do with VNC. To make things more... interesting? XYZ must never go out of the corporate LAN and if it were Open Source, the better. Any ideas on XYZ? Best regards, Amit. PS. Erm... one last thing. If there's a solution, could it include sending the audio as well?
