Amateur radio IP networks. What's out there?

cross-posted from: https://lemmy.sdf.org/post/20077977

What cool stuff is going on with IP over ham radio? I want to build simple services accessible to other hams in my area, and would love to learn about what's out there.

• New Packet Radio: This looks pretty cool, although until the FCC makes a decision on updated VHF/UHF bandwidth and symbol rate restrictions, I'll hold off on buying any dedicated hardware

• Broadband HamNet: I'm not sure if there's any existing network in my area. Since it's 802.11 with yagis and amplifiers, I feel like you'd need a good density of local users for anything cool to develop.

• AX.25 with TCP/IP: I might play around with this. It doesn't require equipment except a UHF/VHF radio, antenna, and a computer, so it might be easier to convince others to try it too. Obviously you're very limited in bitrate, but it would be fun to set up a gohper hole or a BBS.

Are there other technologies or projects worth looking into? Even though I'm not personally interested in buying new equipment for it, I'd still like to hear what's out there.
