title: How do I enumerate web part types in WSS site
body: <p>How would I go about enumerating the web part types available to be deployed to a web part page in a particular SPWeb by a user on a WSS 3.0 site?  Sort of the equivalent of the list that you'd get via the "Add Web Part" link, but in a collection so that they could be instantiated and then added to a page.</p>
