I'm trying to pull together documentation of the scsi layer and link it into 
the index I'm trying to put up at http://kernel.org/doc, but I'm working 
under the handicap of never having used scsi hardware.

Technically I still don't own any scsi hardware except a scanner I've never 
gotten to work, but the scsi layer has now eaten my ide devices, it's 
handling my new sata hard drive which makes sas look even more hilarious than 
it did in 2005, and my vague impression is that the bsg patch turns my 
intended-as-joke question to James at OLS (so when do ramdisks start going 
through the scsi layer?) into a potential reality.  (Not that I pretend to 
understand the bsg code.)

I also didn't understand the rest of your message well enough to comment on 
any of it (does my USB key have a LUN?  The scsi layer grabbed it...)

Don't get me started on udev.  As far as I can tell, Greg KH disagrees with me 
on every topic I've ever raised with him...
