I had a play with this.<p>There is demand for something like this. People want to make a simple table available to Java Script. A table that is easy to edit online.<p>I have seen a few people do this kind of thing with google docs spreadsheets. You can download a table as CSV from google docs. Or do table read/write via google-spreadsheet-API.<p>The growth area looks to be mobile apps. I have seen quite a few people on stackoverflow wanting a simple online table of data for mobile apps.<p>My interest, I want to make building web apps as simple as using a spreadsheet - <a href="http://www.cellmaster.com.au/#HN" rel="nofollow">http://www.cellmaster.com.au/#HN</a>
