I guess you won't get the feedback (and flames) before submission.

What people may want is raid1 across local and iscsi/nbd devices.

What you describe seems to be a (iSCSI) developper test case : The
userspace should avoid feeding a multipath map to the DM in this case.

> In other words, does the hw_handler concept need splitting up?
I don't think so : a LU is either 
o presented by a single storage controler model : a single hw_handler
o directly attached : no hw_handler needed

I can't image a valid useful scenario where a LU can be presented
through different controler models or through different kernel
