[Assist] Supported webcams

[bill-auger]

most cheap webcams will work on libre systems - anytime you
consider "modern" hardware, the chances are lesser, that it will
have a libre driver - my suggestion would be to drop the "modern"
requirement, and buy a bunch of cheap-o $6 cams from some local
dollar store or web shop

there are several online shops, that i know of,  which sell only
libre-friendly hardware - i just checked them all; and none have
webcams - i assume that is because webcams are so cheap and easy
to find

that is only general advice, of course - maybe someone else knows
of some specific examples
