Interesting stuff about creating a SiteMapProvider on ‘Tomblog’ (but Tom who?)

Note 1 - I guess he inherited from SPNavigationProvider or SPXmlContentMapProvider as SPSiteMapProvider and SPContentMapProvider are both sealed.

Note 2 - He doesn’t mention caching. I kind of wonder how that would work.

Still, interesting stuff – might have a look sometime as part of my ‘one breadcrumb only’ campaign.
