With the houses thing, a lot of other people can be seen in chat. So if i'm at my house on cubecraft then I can see all the other chat. I asked my friends about this and they said that was happening to them to. Also when I invite people over to my house, the accept and then they go to their house. We can see each other in chat but we are still at different houses and we can see a lot of other people in chat. When i'm at my house and press tab I can also see a bunch of other random players that I don't know. In the first screen shot I captured I am abbywabyabby, (of course) and those are a bunch of random people I don't know. In the second screen shot I captured I can see them all talking in chat, and they can see me talking in chat.
