Small spreadsheets

3 machines at work, 7 at home, and I occasionally need a spreadsheet on all of them. Office is too expensive and overkill, OpenOffice is overkill. I need something lightweight. Trying out Spread32 at the moment. A couple other choices at tinyapps as well including visicalc. Actually I’d love a server-based spreadsheet, a self-hosted open source version of this, so i wouldn’t have to install anything or worry about moving my spreadsheet files around with me.
