People we're uncomfortable with the idea of a PC being able to eject another PC from the back of their taxi. There is no effing way I am dealing with the backlash from you all if a property manager could eject you from your housing or access your pad when you were away.
As for viewings, yes it would be cool but every pad is different and the difficulty of automated showings may not be worth the effort.
My IC reasoning for this is that housing is so scarce that even corpie characters just take what they can get. It ain't perfect but making it better may not have the ROI in terms of time, that we look for in a mid length project.
