1. Single Initiator - Single Target
2. Single Initiator - Multiple Targets
3. Multi Initiator  - Single Target
4. Multi Initiator  - Multiple Targets

Most SCSI implementations have reached "2" of the above.
The SCSI spec allows for all of the above.
Whether or not you can do "3" or "4" depends on how well "SCSI"
has been implemented on the particular hosts and targets you have
in mind. A number of SCSI implementations can't handle "more than
one thing at once". This is either because their designers didn't
design the functionality in, or they couldn't be
bothered to test/fix/get-the-thing-working.

The answer to your question is therefore: "It Depends.....".
My guess is that if the Target is a disk drive then you should
be able to get a disk that can work with multiple hosts.
If your target is a tape/printer/plotter/scanner then you might
have to hunt for one that supports this featurism since multi-host
support ain't much of a issue for these types of peripherals.
