Hyperscript Spreadsheet Tool in Runtime Product

Has anyone tried to write a Runtime version of the spreadsheet tool for Hyperscript Tools. I would be interested in anything anyone has done. My users need a spreadsheet interface and I don't want to purchase the full development copy. I was just at the Worldwide conference and a system engineer mentioned that she has heard of something to this affect being done somewhere. If no-one has heard of this, any ideas on how to do it would be greatly welcomed. I'll give it a shot. Greg.
