[Tinyos-help] send - sendDone delay (MICAz, T2)?

Sending uses CSMA with a random backoff to avoid collisions with
packets sent by other motes in the network.  On the CC1000 you can
change the backoff value by implementing the CsmaBackoff interface and
wiring it into CC1000CsmaRadioC.  I'm not quite sure how its done on
the CC2420, but I assume there is probably something similar.
