I like the idea but customer service and uptime guarantees could be a problem. It'd be worth paying a bit extra for customer service who will converse & troubleshoot with you knowing that you're not clueless. A proper data centre provides many benefits though. Two big ones (excluding security) are redundant networks and power. A good UPS would probably suffice for power though. I think I would try it with a hobby site or two, but nothing critical.
