As mentioned in my previous post, I have been playing a bit with WSS search today. As a result, I finished a small user control mimicking to some degree the free CorasWorks WSS cross-site search Web part. You can download the sample from the U2U SharePoint resource centre where we hope to make other samples available in the coming weeks and months. If you are interested in having your sample made available via this site, let me know (patrick@u2u.be). We could make this a central place for smart part ready user controls :)
