Metricom Ricochet: uses 162 channels in the 902-928 MHz band; Every radio listens on its own unique pseudo-random sequence of channels, changing channel every 25 ms. When it wants to send a packet to another radio, it consults its internal tables, predicts that channel that radio will be listening on at that precise moment in time, and transmits the packet on that frequency. Stanford has written a Linux driver for sending IP packets.
