Hi,
I either don't understand the answer or you got my question wrong.
By sharing the Screen I mean... Seeing the contents of the other machines Desktop. Similar to what "remote Desktop" or "Teamviewer" does. Letting you see the contents of the Desktop from another machine in realtime.
I do not need the ability to also control another "machine" - I just want to be able to see it.
In particular - I want to see in realtime the contents of the host desktop on the Guest machine. The tricky part is that the Host is not connected to the internet.
