of course, of course.  I agree with you.  There are lots of things not discussed, such as technical detail about coming phone apps.  Where is the github for that?  Will there be mechanism to buy berries in apps with fiat or user have to inconvenience themselves at exchanges to buy berries?

What about crowd funded security deposits?  How does one makes 7% annual return on it?  Once berries are put in to crowd fund, can you cash out anytime?  

What if berries value triples, quadruples?  Does renter receive partial berries back or landloard just keeps the berries?  When security deposit is returned to renter after vacating premise, does landlord have to pay back in same berries as value of berries will fluctuate.

What about legal side?  How does landlord goto court to evict dead beat renter?  Will paper contracts needs to be signed for court document purpose?  

There are so many areas that are not clear.  As they say devils are in detail.
