I will attend the SharePoint 2007 conference in Berlin next week together will a few other Mondosofters. We will have a booth in the exhibition area where we will be able to give you a preview of the upcoming Ontolica Search for MOSS 2007.
I am also going there as a speaker. I will present the Microsoft session IT06 - Search Technical Drilldown on day 2 at 11:30. You should attend this session if you would like to get a better overview of all the great improvements to be found in MOSS 2007 search. The session will also include a few demos on customizing various aspects of the MOSS 2007 search.
