I suspect you're right that Jim McGrath didn't report any end user
software, but then I did and I recall some others doing so.  As I said at
the meeting, the HP Vectra XU 6/200 PC that sits on my desk, containing an
Adaptec AIC-7880 host adapter and (among other devices) a Quantum Fireball
disk drive, configures itself using SCAM very time I turn it on. 
Including, for example, this morning shortly before reading your message
and writing this response.  When shopping for this system, I looked at
comparable systems from Dell and Micron and others, all advertised that
they came with SCAM support (sometimes described as Plug and Play for

Incidentally, a more expensive configuration of my system comes with a
Seagate Barracuda disk, so I know Seagate's disks at least tolerate SCAM if
they don't actually implement it.

Systems that use SCAM are quite easy to find if you open your eyes/mind
enough to look for them, rather than deciding in advance the answer you
want.  Of course, I suppose you could respond that this is a system or
hardware, not the "user application available software" you say you're
looking for.  SCAM implementations are ubiquitous in SCSI BIOS's, but make
little or no sense for application level software.
