.xls Anyone?

I am building a spreadsheet to demonstrate the effect that dilution has on an early investor (angel, seed etc.) and the subsequent effect of certain anti-dilution measures that early investors may employ to keep from getting wiped out in later financings. If anyone has such an .xls built already I would love to exchange documents with you. Please email me if interested.

This gives me an idea. How about a web-destination that would enable the sharing (or sale/purchase) for such documents, like .xls models, .ppt templates etc. It could be something like an MSOffice eBay of sorts. If you elect to run with that one I hope you may cut me in for some founders stock or at least give me a footnote in your biz-plan. Thanks!
