I've worked in places where teams have created "war rooms", basically a commandeered conference room where everyone hunkers down around the table and gets the project done (this was when I worked on a mechanical device and we needed to mess with parts and tools).

The benefit of the pod to me is that you can make the closable offices way smaller (desk, small table, couple of chairs) when the doors are open the offices become part of the larger project room. The entire project room can also be closed off for noise, privacy, meetings, stealth, etc.
