No argument there. Plus you don't even have to be on the same continent
as the drive you're reading! Blocks of MAC addresses do cost money, but
Microchip sells them a la carte nice and cheap.
A few years ago the sensible thing would be to use SCSI. SCSI-1 isn't hard
at all, and *that* crowd is totally cool about vendor IDs! Email them your
8-character name, they say OK, and now you're safely unique, for free. But
it seems like these days everything everywhere is about making people keep
paying you fees forever. They must teach that in business school...
I've been working on a couple of coupler designs

Looks like fun and the price sure is right.
