Multi-instance Widgets

There was a thread today on Wp-Hackers regarding multi-instance widgets.  While I don’t need this right now, I was curious because I expect to do something with widgets for my wp-SwimTeam plugin.  If and when I do, I want to make sure I don’t design myself into a corner.

The discussion referenced an interesting article which outlines how to develop a widget to ensure it will support multi-instances.
