You seriously need to get a lawyer, just because you're using bitcoin doesn't mean you don't fall under any jurisdiction. You are governed by your state and national laws. Financial laws don't just apply to money, they apply to a wide range of assets classes. Plus it's not just money lending laws you need to be concerned about, look at the action letter served by the SEC in 2008 against peer-to-peer lenders for serving as an alternative investment asset class without proper licensing. The same likely applies to you. Proper legal works will also protect you when one of your users sues you (which incidentally your insurance is unlikely to protect you against unless you negotiated a specialist deal) or the feds bust you when your service is used for money laundering (as has happened to other bitcoin financial services). You should be able to legally setup and operating a bitcoin lending platform, but you need to make sure the paperwork is in order. You probably need either a specialist lawyer in the founding team or at least someone with deep experience of the lending space who can guide you through the hurdles.
