[Spread-users] getting 2 daemons to talk to each other?

 From your email, it looks to me like you're listing the segments in 
different orders for different daemons.  You shouldn't do that. ;-)

Typically, the Spread.conf file you use should be identical for all 
daemons.  The only cases where I have needed to do otherwise were to 
print different Alarm flags when debugging Spread itself.

Hope that helps,
