I should have said that "the pieces to build them are already available _in browsers without the need for using extensions or plugins_" or something similar - I think this is what is put out as the differentiating factor in the rtcweb charter. Anyway, I seem to be rather lonely in my corner of the room, but I maintain my opinion that we should defer this to a later stage. > > Emil > >> >> So my 2 cents say: let's push this into phase 2, and focus on getting >> phase 1 out in a timely manner :) Sorry for not being enthusiastic. >> >> On 2011-09-19 09:02, Magnus Westerlund wrote: >>> WG, >>> >>> There where some discussion in the Interim meeting last week about a >>> Screen/Application/Desktop sharing support use case.
