I think this is a good idea, I'd also love to see VIPs being able to buy houses and rent/lease them to other players. Something like in Crazy Bob's server with a command to open your garage door and a remote starter for my scooter would be cool too
That way, we will be able to have our own little economy and currency, on top of the unique Plan B vehicle plates!
Oh, and also it would be really awesome to be able own pets and feed them periodically like /pet and /feed Tounfish
