[Battlemesh] [FCC] What hardware still works?

[Ben West]

Is JTAG intervention now required?  I had thought I'd read that serial
console access and/or TFTP recovery mode was sufficient, at least on
TP-Link products being discussed.  Since we're talking about products
costing only 50-100USD, I would gather that the amount of effort
manufacturers are willing to invest in locking the firmware is finite,
meaning by extension the effort required to work-around such locks should
also be finite.

That is, all radio products with firmware presently for sale can have their
firmware modified, given sufficient effort.  The fact that sufficiently
determined persons can override countermeasures and mod the firmware
doesn't appear to endanger their FCC certification.

Anyway, similar to the hardware compatibility pages on openwrt.org's wiki,
would it make sense to also record in wiki the list of working hardware,
along with known work-arounds?

What would be a good venue for such wiki pages?  Any of these?
