So we're back to the issue that nobody in the NetBSD community maintains 
the SCSI sub-system in any way comparable to how, say, the LFS or the USB 
or the VM code is maintained. I am currently looking at the SCSI tape 
driver because of QIC drive problems, and the claims of superior NetBSD 
code quality ring badly in my ears.

When are we switching to CAM?
