The desired project will include a downloadable application that will allow 2 or more people to share screens on a local Internet such as people that are on the same local net at home or at a meeting room, etc.
One person will be the lead and the others will be the listeners and it will be possible to change roles on the fly.
Session starts when the lead starts the application and decides on a password. Anyone else on the local net can start sharing by starting the application and providing the same password.
No need for voice interaction over ip or any special feature.
In the future it may be desired to add also smartphones eg iOS or android.
