I'm copying this discussion to the ecs technical  list.

I'm extremely uneasy about such a setup.  Having worked with mainframes years
ago with two-tailed disk drive controllers attached to separate computers, i'm
fairly certain that the usb hub does not come close to providing the locking
and protection mechanisms that the old dasd controllers had.  Bear in mind
that in the PC world, most of the DASD controller function has been moved into
the device driver, so there is no awareness of multiple access paths.
