Possible Party System?

I have been playing Rust for a few days and it has been a lot of fun running around by yourself trying to survive. I know this is still alpha and there is a lot more to come with this game, but teaming up with people as of right now isn’t a complete viable option.
When someone builds a base and puts a door on it then the person they are teamed up with can’t open it. Maybe make a way so people can group up like a party system or be able to set permissions on your doors for who can open them and what not.
Please leave your comments on what you think about this, and have a fun time surviving in Rust!

I agree and I also think that it would be awesome that if your friend invites you to a game you can spawn on them/ near them, as the only time we found each other so far we got shot up 3 seconds later.
