I am guilty of hijacking the thread, tho i plead that it was inadvertent. :-P
indeed, ZAC/ZBC is orthagonal to multipath, no arguments there.
My response was directed to Mike's discourse on the available testing tools for device mapper and contained my ruminations about how to leverage those tools for the project that I am lucky enuf to be working on.

ZAC is a different beast altogether; I've posted an initial set of
patches a while back on linux-scsi.
But I don't think multipath needs to be changed for that.
Other areas of device-mapper most certainly do.
