We have developed an application for collaboration with documents in various format. With our system it's possibile to organize meeting sessions and sharing documents with any device to collaborate realtime with digital ink (similar how to with Lync, but with more format support and multiplatform).
We have found this guide (http://technet.microsoft.com/en-us/library/gg398068.aspx) to integrate with Lync menu; but we would to know if there are licensing restrictions or not.
Thank you in advance
