Widgets

I have seen widgets on some library pages -- for IM, for example.  But when I looked at Heather's WorldCat widget I realized that those handy search boxes right in many Google results must also be widgets.  I love those, and they make a lot of sense in libray land since so much of what we're about is searching and finding.  Maybe widgets for my most-used databases?  The library catalogue? Customizable ones for our users who are so inclined would make a lot of sense.  Must investigate further.
