zeroconf 0.9-1ubuntu1 (ia64 binary) in ubuntu feisty

 zeroconf is an implementation of IPv4 link-local addresses (RFC3927)
 which can be used for ad-hoc networks. Addresses are allocated from
 the 169.254.0.0/16 range semi-randomly.
 .
 That means making it possible to take two laptop computers, and
 connect them with a crossover Ethernet cable, and have them
 communicate usefully using IP, without needing a man in a white lab
 coat to set it all up for you. (from www.zeroconf.org)
