One of the other Academies I'm has added a Vanguard Section. Since they didn't like BYOND, they use
Cray Online and
Evolve. At the basic level, Cray Online works similarly to BYOND's Cardfighting system. The difference is that Evolve is just a bunch of chatboxes rather than a place where you can roam around.
In order to connect to each other (no spectating unfortunately), both players will need to join the Vanguard Group and need to be in the same party. Cray Online will use the IP provided in the Evolve parties to connect to the other player.
If you'd like to try it out, my Evolve name is Xaqairy. Add me as a friend and I'll invite you to my party.
