This could make for a good use of this software. The biggest issue free software such as this have is still adoption by less technically inclined people and a steep learning curve for techies. More effort needs to be put into cognitive reasoning and user planning but these skills aren't typically focused on by computer scientists. Whereas something like this absolutely needs to just work for it to gain traction and be useful for anyone other than niche teams capable of designating it as the defacto tool. If there are obstacles people will usually switch to the lowest common denominator like Google Hangouts or whatever they can use without installing something. It could be a good Skype replacement but the challenge is focusing on usability in conjunction with functionality.
