Well that was always my problem with Facebook's implementation as well. If I'm paying money for virtual real estate I'd rather just pay money for the server and then control it myself. It never made sense to me to let one company host the code, because there's literally no benefit to me for them doing that. Usually the benefit of letting a company host the code is that it costs less money, but if I'm going to be paying virtual rent every month anyway I'd rather just have server access.
