I'm watching the development of the Universalist Orthodox Church with a lot of admiration and a little bit of envy. In about a year it has grown to four parishes and two emerging missions. (Their site has a new page that better explains their approach and what they mean by Universalism.)
Are any of these parishes large? No. Do any have a building that they own for worship? No. Are their clergy compensated for their labor? Doubtful. But do they exist and grow? Yes. Do they ordain or receive new clergy? Yes. Do they have regular, public services of worship (liturgies)? Yes. I'll take what they have over the unrealized plans for a large institutional church any day.
What what would it take for us on liberal Reformed end of Universalism to have four parishes and two emerging missions? That's behind so many of the articles I write here. I'm fortunate to live in a city with a Universalist Christian church, where I am a member and preach occasionally. There's one in Providence, and Tokyo. You might find others, historically related to the Universalist denomination or not. If I were in a city with a Universalist Orthodox church, I'd probably attend liturgies, at least occasionally. But people in most places don't have the option.
I'm not going to build a church where one's not needed but you may need to do so. A monthly service of morning and evening prayer led by a lay person for a congregation of three is a hundred times better than wishing that there was a church.
What would it take for the Universalists to have four new churches? A hundred? Even one? Most of all: desire to have one, even if there's no institution "out there" to help. (That said, I'd gladly do what I could to help a new church. I bet others would as well.)
