There was a twit.tv podcast on this a few years ago in the context of IP
connected security cameras. They walked through the ideal topology for a
home network where 10-20 IP cameras are hooked up to a small
NAS/Zoneminder computer. I can't find the exact video though and it had
some relevant ideas.
What are you planning to do with these Zeros? Are they going to be part
of a cluster or just doing randomly things independently of each other?

Zeros, for those who don't know, are $5 512M/single-core ARM devices
with only a micro-USB OTG port for connectivity. If you configure them
correctly, you can provide power and networking over the same cable so
there's not too much cable clutter added.

So far I've succeeded in building a version of OpenWRT that runs on a
Pi 4, which has standard USB ports. I've plugged a four-port USB hub
into one of them. As Zeros connected to the hub come up, usb<n>
entries are created in the output of 'ip addr'. I added an interface
that bridges them together, gets them networked via DHCP, and
generally convinces me that what I'm doing will work.
The question is: what's the best way to integrate them into my
network? I'm not sure I need another OpenWRT box, as most of what it
does -- firewalling, dhcp, etc. -- can already be done by my gateway
router. Really the only requirement of the box they connect through is
that it have a USB port (which my Ubiquity X doesn't). If there were a
package like OpenWRT but focussed on load-balancing rather than
routing perhaps it'd be a better choice.
Thanks!
