Great idea. I hate it the way you launch an application - because you want to use it, and instead of getting your work done you are prompted to download and install an update.

It would be very cool if there were also an optional Sparkle Update Manager application or preferences pane that could be downloaded and installed, which could optionally centralize the update process. An application could check in with the Sparkle Update Manager if it’s installed, and if this checkin is successful, all updating would happen via its embedded engine instead. This would have a few significant benefits:
1. It would make it possible to update all Sparkle-using applications with a single click. Just open the Sparkle Update Manager, click “Check for Updates,” and any of your applications using Sparkle would be updated.
2. It would provide a single place to set preferences for application updates — whether to check for updates daily or weekly or only on-demand, whether to send system information with the update request, and so on.
