[support] Google Spreadsheet

While I see there have been discussions of implementing a Google Spreadsheet-like feature for Drupal or an API to share data with an actual Google Spreadsheet, I don't see any working code.

Does such a thing exist? I have a site where the owner wants to keep the list of Drupal users (complete with a set of custom fields) in a Google Spreadsheet. My only solution is to hook into the registration form processor and use curl to post the fields to the Google Spreadsheet. This I believe can be done and would work. Updates are not yet accounted for, but I'm not sure this will be a requirement.

Anyone have an alternative solution?

Thanks!
