I want to be able to let some people into my house too, and keep others out. =p It would be neat to designate one home as like a LS hangout if they don't actually allow us to have such things.

Edit: I remember in Monster Hunter Tri they just had like 4 character passwords for housing in that game. So you just gave the pass to those you wanted in. But you didn't have to lock the house either. Lots of options is best. ^^
