I have a rudamantory system working at my location right now, it acts 
just like a xband digipeater using digined 0.4.0 cygwin version, agwpe 
drives the radioports and xglue makes a axudp link to a second agwpe 
connected to ui-view.

the digined digiend rule makes sure that all frames are transmitted to 
the axudp port even if the path is already used up.
all I need to do if set the first digi in the digipath to the call of my 
gateway and ui-view transmits out onto 144.800 trough axudp and the 
digined software.

Now while you guys keep arguing and debating I'll go back to setup a 
digined as a tier2 hub.
