I've heard of targets for iSCSI, which of course is just SCSI over a
different type of cable.  Since a lot of OS (including Linux) support
iSCSI initiators, if you need SCSI emulation without weird hardware
hacking, an iSCSI target may be a good way to go.

I don't have pointers to specific examples handy.
