I'll reply on this thread: No it isn't.

If You think of SDIY also as a playground for the techies and the
preservation of the commercial products.

There are some "precious" instruments that will become brain-dead
after the mask-rom CPUs run out of their CMOS juice. These will be
gutted/dumped, if there's no commercial or personal interest doing
things the hard way of the reverse engineering.. Now, If somebody gets
the firmware out to burn on the chip, (s)he's a Dollanier ;)

I'm also on personal - consumer level - interested on so-called
"security" sold to me. Or let's put it the other way:I'm interested in
hacking things.
