I tested with SmartOS, FreeBSD, and ZFS on MacOS against ZFS on NetBSD.
NetBSD is missing some of the features of the others, but a zpool
created with NetBSD was able to be imported and exported on the others.
I keep a thumb drive with a pool on it for purposes of transporting
between the OSs.  Going the other way around I found to be a bit harder
and in some cases resulted in requiring the pool to be imported readonly
due to unknown features that NetBSD ZFS didn't know about.
