If you're using jquery, just use ajaxStart / ajaxStop.

With the UpdatePanel, there is an UpdatePanelProgress control to display to the user a progress status message.

Definitely #2. Adding an UpdatePanel is a whole can of worms, and if you're not using them already on a given page, adds a lot of overhead.

The code involved in using jQuery to do this is trivial. There's a nice little plugin called blockui that can be used to render an effect and disable all controls on an area. It's not too hard to do this without the plugin either, but why reinvent?
