Great carsonfarmer. 
On point 2: How and what tests have been performed, can you please share the method and tools used, because I am in the process of evaluating IPFS performance for our product.
On point 3 & 4: Interesting it is, when we tried to run IPFS in mobile, it was consuming lots of mobile resources and we dropped it. How do you decide on when to use the mobile peer and when to use the server peer? and what tech. stack do you use in the mobile to interact with IPFS?

Thanks in advance.
