the good news is that you can simulate things by useing UDP broadcast 
packets as your transport layer.

don't get fixated on the idea of using satellites, as a means for 
publishing updates a high-powered AM or SSB station can blanket a large 
area, and the efficiancy gained by only transmitting things a couple times 
(including error correction to deal with missed packets) instead of once 
to each destination can counter the drawback of a low bit rate.
