I've just installed and played around with the Infrastructure Update for WSS 3.0 og SharePoint 2007. Finally SharePoint has federated search capabilities and an improved Search admin dashboard - both where "user friendly" when it comes to setup and configuration. Federated search connectors are available for several search engines, and/or you can write your own for searching your internal business application sources.
The obvious next thing for me now is to create "the ultimate?" search dashboard combining: faceted search, ontollica wildcard search, federated search and custom search (against our business systems). I think it will be quit good ... at least I hope so :-)
