Fred,
I think setting up a wireless TCP/IP link would be fun. You could run 
some kind of IRLP/EchoLink connection over it. I just wouldn't try to 
make an igate that way if you didn't have to.You are introducing several 
points of failure into the system and it isn't gaining you anything. It 
is kind of fun to have the igate where you can see it and watch the 
traffic. There are a lot of adjustments to make with an igate that can 
take some time to get set right. You will be experimenting with filters 
on your Internet connection to avoid just dumping the whole worldwide 
feed into your igate and setting filters on the output side for what 
gates to RF. Another thought - if you have extra radios set up a 
sat-gate. I don't know exactly how to do that, but I am sure there are 
plenty here who do. It is basically an igate on the frequency used by 
the PCSATs.
