I enjoy doing relays and other team activities but usually stream delay (adding alot of time) or heavy lag (invalidating runs) factors into it to much.

As such i was wondering if there would be some website or something where a virtual computer could be setup to avoid such issues.

It should be able to have multiple people have control at the same time.

It should also be able to be streamed and ran for multiple days/weeks upto maybe even a month at a time

Is this a question about a specific game? You’re talking about invalidating runs but I’m having a hard time visualizing what game you’re talking about.

It sounds like you need to contact the mods of the game in question to find out what their rules are regarding a single virtualized environment for players doing a run together for a multiplayer game.

All I can tell from this post is that maybe you want to have multiple people play a game off one computer over the internet? I'd recommend parsec for that https://parsec.app/
