Now that you can set up Google Docs for Offline working, it'd be interesting to make Smath interact with their spreadsheet.
Another suggestion for plugin developers: you might consider making use of wxMaxima at

Edit: nevermind, it seems that offline editing is available only using their browser.

Gspreadsheets supports offline viewing from Chrome browser.
