  As I understand it, during transmit, each card looks at what it is supposed 
to be sending, and compares that with what is _actually_ being transmitted.  If 
they're different, it assumes a clash and waits a random amount of time before 
trying again.

  That's what I love about avtech.  The subject always changes, and you never 
know how, why or in which direction.
