Another idea is to sub-lease un-used space of a business. A couple investment banking firms in Manhattan that have significantly downsized have rented out floors to start-ups. You get free phones and private WiFi as part of the deal. My friend's start up is doing this and its pretty nice. There are a couple of micro-startups (3-5 employees) on the same floor with his company right now, so it got that "incubation" feel.
