Curious, which part is reinventing the wheel? If you're referring to the /bin/login hack, imagine instead, it's BBS software. (I had a lot of fun accessing my home computer from across town with a Psion 5mx and a Kenwood TH-D7! No practical value, just a good challenge.) As for the APRS-IS bridge, that would be quite useful for bridging relevant APRS-IS traffic within a given radius to LoRA, and vice-versa.

Also, I'm quite aware of IP over AX.25: I generally prefer to avoid that extra overhead for my intended applications. The stack I wrote exposes a BSD sockets-like interface to make it easy to make lots of software able to participate in the AX.25 fun, and even compiles on PowerPC Macintoshes for what it's worth.
