Taking all the demos for jhs together you can make an interesting application.
What is needed is some form editor to let you extend and place the demos on/in the browser. It is relatively simple to do because the demos are already there for you and doing more or less everything an application wants. You may want to place fixed text, graphics and grids, change number of rows and columns and all of it is simple. It would be nice to combine it with a database like the mapped file database. So most of the ingredients for an application is there already. I have used this and it works fine. It would be nice to package it for easy use in a form editor.
