How about with four stations, each in pairs of two sending to each 
other?  Six?  Ten?  Twelve?  (GRIN)

Where does it fall apart with the "hidden node" problem?

Packet did... D-STAR will too... 1200 baud just isn't all that much 
bandwidth.  At some point the network becomes "saturated" and the 
re-tries from hidden nodes not being heard by all, effectively jam the 
frequency.

The throughput can be charted... a few stations, things are good... a 
few more, it *exponentially* gets worse.
