Hi Dave,
I'm sort of in the same boat. I was looking at getting my packet gear running and all the VHF packet out here is gone. So I tried HF packet and the NET105 group is still alive but woof at 300 baud it's hard to take. There was just an FCC Part 97 change that allowed 600BPS so I haven't retooled to try yet but I think that's the next step here.
I've also been looking at the mesh options. I like the ARDEN concept and I had friends who were playing MESHNET MMHHSS type stuff a decade ago but it all seems to have fallen off. Here I can't seem to get Ham's to believe that our licenses are for operating radio stations, not just talking over the radio so it's been difficult to find anyone who can see using their license to mesh together computers. I do see that there are some counties and areas around NY State that have got it going and Oswego County in particular has a ring around the county which is awesome.
I think you could do the BBS via ARDEN but that's just because ADREN becomes the carrier vehicle for the IP data.
So you might want to look at New Packet Radio too that's sort of cool

And here's Broadband Hamnet

I've been looking at Meshtastic too but haven't moved on it. I've been rebuilding a BBS here and so many things, so little time.
Nice to see that you got your station running again.
