Pretty much anything you&#x27;d like to do with CouchDB or MongoDB. Replace &quot;document based storage&quot; with table based and you have pretty much any *SQL application.<p>So I guess my question is: How do you expect people to use your fine grained model with databases? If the answer is &quot;not at all&quot; then I find the scope too limiting. If the answer is &quot;1 grain == 1 db&quot; then I find the claim that you are solving difficult permission problems to be false.<p>Note: I don&#x27;t want to be too critical here, I&#x27;m just trying to pick holes in your claims of scope so I can categorise the power of sandstorm and how far it could be useful for things I&#x27;d like to build.
