Seems like a solid project, but I can't fathom how one can possibly hope to create a scalable distributed network that can handle bulky media network traffic while also promising anonymity. People usually have a hard enough time tackling those problems separately.
I share your thoughts also but according to the team this is a research project and its normal that it has complexities. In this sense, we should rather trust the ability of the team to deliver it.
Since this is a research project do you worry about how long it can take to achieve some of the items? Do you have any concerns that the timeline can get stretched out much longer than the planned roadmap?
