Jonathan,

"Voice", "Video" naturally aid the "textual" communications. The next frontier is "3D" communications. For e.g to discuss the internals of an "Room" during Interior-Design, discussion of an back-injury during a healthcare session etc. I would like to present our work to you and your team in this context. We have been granted a patent by USPTO. http://www.google.com/patents/US8935328
We have also had market-validation for this.
