Obviously the concept works fine if there is a deep pool with lots of churn and the house can take a fee on every transaction, sort of like if we all traded houses every year and realtors took a commission on all of those sales. And if prices are going nuts, then anybody who's anybody can get in and make a killing.

But if the concept languishes with a small pool of die hard acolytes, and the rest of us opting out, then at some point the business model just isn't worth the squeeze.
