zigbee prototyping

Pff, sorry to bother you again for one more question:

The project i'm working on is a prototyping project but i'm also thinking of the way the project would work for real.
So i know that for prototyping i could use the xbee series 1. Using an (USB) explorer i can configure each xbee to be in the
same network, adress range etc..

However, the situation is so that these xbees (max about 10) should autodetect (discover) and connect to a coordinator xbee
that is in broadcast mode. I read in the xbee datasheet
that there is support for this, but this is a peer-to-peer setup, which differs from the broadcast setup, right?

Thanks!
