ChilloutVR is releasing on Steam too late to do the expedition, so it's being put on hold until 1900CT tomorrow.

On top of it coming to steam, at some point it seems like it's releasing a new feature that lets you have closed audio calls with someone in another instance and their avatar gets projected to the room you're in. 

https://developers.abinteractive.net/get-chilloutvr/ has links to both standalone and the steam page, and if you wanna make avatars, you get a well written guide at https://developers.abinteractive.net/cck/

I haven't bothered fucking with avatars since advanced features came out but it should work like SDK2 with the animation override controllers with a few extra slots. The reason VRChat has persistent avatar states is likely because it was taken from CVR, which had it so if you set your avatar to toggle state 5 [spoiler]which pulls my penis out[/spoiler] I'd log into any other instance in that toggle state.

The avatar system is robust enough that people can share avatars with you though, and there's already placeholder avatars made and assigned if you wanna show up for a few minutes to see what's happening at Tuesday on 1900CT. The location will be announced closer to the time picked.

Chillout supposedly unlocks on steam just before midnight on britbong time so it might be worth it to hit download before you go to bed to be ready.
