Paris-based Chorus Systemes SA has closed its Los Gatos, California, and Beaverton, Oregon offices and opened a single outlet in Campbell, California. Most of the 20 staff involved are relocating. A couple are leaving and a couple will work from home in Oregon, Chorus says. The idea behind the regrouping is to have a single sales and engineering headquarters on the West Coast in readiness for its next phase of development, adding its microkernel to Novell Inc SuperNOS.
