I was wondering, as a thought experiment, if it were possible to use Google Spreadsheets to post to a web service.
For example imagine you created a spreadsheet for guests attending a party with columns - first name, last name, allergies, meal preferences since it is so easy to share and sync you send a link to it to everyone you can think of. But being a geek you would like the data to populate a MySQL server (or whatever) so you can create a fancy website or reminder or social thingy (or whatever).
Is this possible? I have tried reading the API but it does not appear to be but maybe I have missed something.
