Multiple initiators on a SCSI bus should work without any problems.
However, this is not a common implementation compared to the more
traditional single initiator environment.  A well designed SCSI
product which implements the features necessary for multiple initiator
(e.g. BUSY status from the device) shouldn't have any problems.

A product designed for a single initiator mass market (e.g. most PC
host adapters) may not have multiple initiator support built in.  A
product designed to implement the full SCSI standard will.

I am aware of one product which will handle multiple initiators on a
PC bus -- Ciprico's Rimfire 5500 PC/AT host adapter (I used to work at
Ciprico and can attest to many hours of 2 or more PCs pounding on one
drive).  I imagine some other high end products (such as from DPT)
will also work.
