[JXTA discuss] creating a peer group and advertising to other peers

I am using the shell and trying to create a peer group and then advertise the new peer group to other peers.

The default peer group is too large and so it is difficult to identify the advertisement at the other peer with all the other traffic.

I am using newpgrp to create the group
I am then trying to advertise the new group using "publish"
I am then trying to pick up the peer group advertisement at another peer by using "search -r" and then polling with "search"

The number of advertisements make it impossible to identify the one sent by the original peer

I am using the shell to identify the steps I need to go through before coding using the API

Can anybody help?
