Well, since people are quoting my second source messages, have a look at:
http://www.etantdonnes.com/Motes/report_mica2/
(which seems to be down right now but will hopefully be back soon...).
However my message speed/reliability measurements use only the standard
GenericComm and TOS1 code. I think the OP was trying to fiddle timeouts
and backoffs to speed things up further. Data mining of the help list
should turn up some more useful advice in this respect.
