This is really coming together as the project that really brings it all together.
The Audio/Video stuff is great and having it fully embedded in the matrix client will be amazing.
P2P is really cool, specially when there is an easy way to have other servers (or your own) temporary hold the message for you when you are offline. Having full local offline matrix with the standard chat client rather then some more specialized tool is a real game changer.
What I would like to see is for Matrix Decentralized Identity to be able to be used as a SSO for other sites.
Great work and great to see that a great business has been built on this technology as well.
