Perhaps simply multiple network interfaces / assigned IP addresses - all could actually reside in the same physical machine. (That's probably not good practice Tor-wise, of course - the nodes should be as dispersed as possible..) edit now that I think about it, placing Tor exits in a hospital area might be a clever tactic to avoid them being raided (e.g. to freeze memory and attempt to extract some data about other nodes etc)..
