I think the issue can be resolved with a Promise returning method on 
the NavigatorPresentation instead of the ```session``` property (as 
agreed in the solution for #19 ). If the page calls the method (e.g. 
getSession()) it means it now switched to the presentation mode and is
 willing to accept connections and environment restrictions. The UA 
could also present user with a permission prompt if it's an 
interactive UI and the page wasn't running in an incognito context / 
started as a response to some page trying to present to the screen.

To join the presentation started from A, B only needs to know the URL,
 not id. Id is needed for resuming/joining a session (vs. 
presentation) started from the same UA. We agreed to remove id from 
startSession(). Selecting the right screen is on the user - if my 
friends and me decided to play a game together, one starts the game on
 the TV, others select the same device and the game presentation 
should be able to accept connection from game clients.

A shared TV could have a browser or an interactive webapp (e.g. 
Spotify) that can be used without presenting (via remote control / 
TV's touch screen). Now I may want to allow my guests to connect to 
the screen to add their music to the queue using Presentation API but 
don't want any info saved - so while the page has connections from 
other clients, it shouldn't be able to save or remember anything. 
Perhaps we should have a method similar to opening a window for the 
page to become a presentation... So the interactive page calls this 
method and its presentation version is loaded in the incognito context
 and is ready to be connected to. We may want the initial page to be 
able to message the presentation one turning it into a special case of
 the Presentation API :)
