I have been working on my own system when I have free time and I currently have two nodes. I have also been working on a prototype stand for a node. I will have pictures or video of that soon. I have also installed an XMPP server and have made a small chatting network. The server supports IM, Chat Rooms, File Transfer and Video & Audio communications (VoIP). I have tested it on two laptop with Ubuntu, one PC with Windows XP Pro and an iPhone. My iPhone is the only device that did not support video because it is a first generation. I am pretty sure any of the newer iPhone or iPad with face time would work. I believe this system would be great for non-ham CERT members or a large staging area like the fairgrounds. Please let me know what you think.
