Well, I'll say this in regards to private venues:
Teraa Matar has something very much along the same lines as what Aldrith seems to be talking about. its basically a communal housing block, where everyone in TRA lives. It actually does a pretty damn good job of encouraging RP, since in order for anyone's character's go go anywhere (like the hangers) they have to go through the rest of the complex. I'd dare say half the RP I've gotten on kiki has taken place there, so it definitely does work, at least in our case.
