Great build by the way!
I have been thinking of running an IRLP board with my PI, but the extra cost has kept me from doing it. I have to put the finishing touches on a 6.5 grendel build first. I am currently running an Echolink node on mine using SVXlink, and a UV5R radio. As soon as I can find an old radio to use for a little more power and eliminating the need for the batteries it will be on 24-7. So far it has worked well, on the first net there was some problem on Echolink dropping, but everyone was experiencing that to some degree, and all of the other testing has been flawless, so may have been something on the conference room end.
