I'm not sure why my comment got down voted so much, my point is if a obscure web address is the only line of security it is terrible, especially as they recommend you to bookmark the address in your tool bar. The point is it might look great and secure at first, all it takes is a small mistake from one of many angles and it's done for. Examples of mistakes, people posting their urls, people being tricked into posting their urls, shared computers with bookmarks, the webmaster accidently installing a sitemap script which indexes them all etc.
I think it got voted down because it has nothing to do with the forum post. The post talks about a "green address" system, not their strange techniques for security, and your comment makes no distinction. I had no idea what you were talking about until a couple hours and several similarly-cryptic comments later, and going to Instawallet's site and seeing it for myself.
