The idea of a neighborhood, being able to drive around, have the water surround sounds awesome. I never use to use ban lines or orbs until someone entered my home undressing my prim babies, yes they may only be pixels, but made me think why would someone do that, the person thought there was again no one home and i caught him come straight into my babies room.
If people enter your home uninvited, what is there to stop them from using your home for their own entertainment. Why not just have the ability to lock our windows and doors. That people if they try to TP that also is turned off. You may only TP to your own home from another sim or be invited in by teleport. There would not be any unsightly orbs or ban lines. Locking your windows and doors work fine in real why not in SL?
