i remember the early website, before houses, they said a theif could lockpick into anyones house if he's gm heheh... never was implemented... the only way to break into houses involved an exploit with standing on a mushroom or rez'ing a ghost in someone's house, but of course there was the exploit i used a few times with castles, you could teleport from 1 square to 1 square, the burning heart guild all they had was pies, so i ate some pies... this one guy had a stack of like 30k leather, i couldn't pick it up but i could craft so i crafted 30k leather worth of armor, 24 hours later the entire castle was moved a few squares over heheh...

but houses are pretty decent i guess, if you have a mule inside it and he unlocks it for you, but the one suggestion i have is that the owner can log out and log back in of their house and not be popped out of the house, or does this already happen? haven't tested it yet...
