I worked at a small IT consulting company in Valhalla, NY and we were part of a pilot with Steel Case for their team and collaborative furniture systems. We had frames on which you could hang screens, white boards etc and all space was otherwise open. You could come to the office and plug into any cube, move people easily to collaborate on short or temporary projects and meet in comfortable collaboration spaces with sofas and plenty of tables. It was the best space I have worked in, encouraged collaboration and destroyed the rat maze. Sadly, the company is no longer in existence (90% of our clients were in the financial district in NYC and 9/11 descimated the company), but the team and the environs worked really well
