The math here is a bit exaggerated. Each rover, at a 15 minute rate,
would generate 4 packets per hour per digipeater. So even with 20
rovers, that's only 80 extra packets per hour - roughly one a minute. A
small price to pay for folks out "doing real radio stuff."
Is somebody actually hears 120 digipeaters in one location - then yes,
they would be a bit swamped. If somebody hears 120 digis - they're
swamped to start with.
