I did a presentation at the Norwegian SharePoint Community (#NSPUG) meet-up yesterday. The presentation and code samples can be downloaded at http://cid-9ecc38025e460fc4.office.live.com/browse.aspx/.Public/%5ENNSPUG%202011-02-15
The presentation covers how you can utilize FS4SP as a data retrieval API outside the regular search page. The samples are simple, but shows the idea of expanding your toolbox with search as an API.
