Sending a desktop to a big screen

[Amit Prahesh]

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?
