Thanks for the input.

I wondered how it works with something like a 4 level set of zfs fs.

/rmh/host1/someproj/Acollection
/rmh/host2/someproj/Acollection

Seven filesystems in all assuming a .zfs at each level.

Now, if you wanted to send receive the whole works you would not be
able to send/receive a snapshot from /rmh/, right?

So you'd need to send/receive all seven then, eh?  Or is there
something like the -p operator to 'zfs create -p [...]' that can be
invoked to allow you to send/receive the whole batch in one go?
