[jdev] GSoC Ideas

[Niklas Andersson]

I got no feedback on this.

I will see how other implementations are doing this and see if we can 
come up with some consensus about how to handle 
media='applicationsharing' with respect to signaling.

If someone would be interested in making use of fully open source 
Enterprise Level Desktop Screen Sharing using RDP, feel free to check 
out the branch that will find itself upstream and become FreeRDP 2.0 [1].

And would someone like to hack on it, for whatever implementation, feel 
free to contact me. Also the Pidgin-project has put it up as one of the 
ideas for GSOC 2016. [2] (In the bottom under Advanced Features)
