I think this demonstrates the potential of my NewI\O concept. Since my system was developed from the ground up to run applications, NewI\O spreadsheet would not have near the limitations that an Ajax version of a spreadsheet would.
I would like to disagree with the last comment, about it not making sense to share spreadsheet data. The #1 person you want to share data with is yourself. I want an internet spreadsheet so I can access my spreadsheet data and manipulate it anywhere I have access to a computer that is connected to the net.
