No, not really.
However, we could use some manner of removing people from your house once they're inside it.
A lot of folks want to keep their houses open for friendly neighbors to take a look inside them and whatnot. But if one of those neighbors wants to come in and start ERPing or something, there's currently no way of stopping them from doing this.
Everyone in your FC will need to blacklist them, but they'll still be VISIBLE in the house, AFAIK.
Even if it was a command that forced everyone inside the house to zone outside it to the front door, that would work fine.
It also appears like it might be possible to relinquish a house if there's a person standing AFK inside it. If that isn't the most evil method of trolling ever devised, I don't know what is...
