Good idea for a widget, but unfortunately it doesn't seem to return any events from a Google Apps calendar. I tried it with a shared calendar, but got no results. Trying it with a publicly shared calendar (usa@holiday.calendar.google.com) works fine.
Also needs some more configuration options (specifically, number of events returned).

Looks like this does work with Google apps after all; my sharing config didn't save like I thought it had. As for specific number of events, I modified the plugin to include this functionality. I am no PHP guru, but it does work.

Hated the styling, too; not sure why it would be done this way instead of strictly by the designer. I changed the plugin a bit so that it displays the events in an unordered list, and has a message if there are no events. I'll paste it here in case anybody else is interested. (I also commented out the CSS/DIV boxes in the widget config).
