@morph we started standing up instances that federate with the public matrix network about a week ago. there's still lots of missing APIs (it has about 33% coverage), but it's advancing rapidly. In other words, it's late alpha, and should be entering beta fairly soon, at which point you can try experimenting with it in earnest. You could do so now, but it'll be a bit hit & miss (and we reserve the right to break the DB schema from under you)
