LoRa based APRS has taken off, but still remains largely separate from classic 2m FM APRS other than both being ingested into APRS-IS. As LoRa was fairly quiet in my area, I wanted to try and make a cross-band gateway where LoRa and VHF APRS could interact, giving more local info to LoRa users and allowing messaging between the two.

Using the CA2RXU firmware on a LoRa module, you can enable KISS over TCP,and use this to drive the gateway. As I already run a BPQ packet node, which supports APRS and KISS TCP, my first attempt was to add it as a BPQ port along side a 2m port, set them up for APRS, and configure cross-port digipeating. This does essentially work (and can nicely integrate into the packet node at the same time if you wish), but it does lack some fine grained control. In the end I went with an APRX based setup instead which let me be a bit more precise. I've documented both here in case either is interesting/useful to someone.
