If you're willing to go without Python/Ruby, then a hosted Drupal (and it's trove of modules) is perfect for this. Acquia (which includes Drupal's founder) was founded to fill this space.
Thanks, I hadn't heard of Acquia before. Unfortunately I personally need the ability to build out apps in different frameworks because I'll almost certainly be extending their functionality beyond CRUD operations and I'm not personally fond of Drupal.
However, I'll definitely be checking it out for simple throwaway stuff.
