I recall that years ago, when I needed to share storage from my Linux box to my PowerBook pismo, I used ethernet and the globalSAN iSCSI initiator for Mac OS X (which is no longer freely available AFAICS). When I said that I had used the SBP target driver before, I misremembered that iSCSI target setup.

I don't know the answer. I have successfully used the Linux sbp2 host driver in the past, and will probably need to use it again. Likewise, I can see myself using the sbp target driver in the future because that might interoperate with MacOS 9, and might provide a bootable device to the PowerMac ROM. iSCSI cannot do those things.
