Funny, there was an April Fools website about 3 years ago that was exactly this concept.<p>&quot;Hey, pay us in escrow while you&#x27;re still motivated and inspired, then we&#x27;ll rake ya when you falter. Bwahahaaaaaaaa!&quot; (in a humorous way)<p>All of the links to sign up just popped up a &quot;Just kidding! April Fools!&quot; link. My google-fu is weak, apparently... Not finding it now...
