There were some questions at the talk that didn't get precise answers.
From wikipedia (https://en.wikipedia.org/wiki/LoRa):
"The LoRaWAN data rate ranges from 0.3 kbit/s to 50 kbit/s per channel."
I haven't found anything yet that talks authoritatively about packet
size limits. A Reddit user suggested the maximum packet (payload?) size
was 255 bytes, but it's Reddit, so apply appropriate error bars.

Summary:
Meshtastic is an open source mesh network application for low power
IoT devices. Rapidly reaching critical mass in Portland due to a fast
growing user community and low cost and accessible platform, it
provides an appealing playground for off grid and secure
communications experimentation and infrastructure design. This talk
will cover basics of the wireless tech, platform and hardware as well
as demo introductory usage with built nodes.
