Okay, I know (hope) I'll see this in the manual, but would like to
ask ahead of time. IF HFS is indeed going away and zFS is the way to
go, does that mean there is a "shared" zFS ala HFS?

Didn't I see a recommendation from IBM a year or two ago not to put multiple
file systems into a zFS? A statement of direction, maybe?
Give that man a cigar!
z/OS V1.7 is planned to be the last release to allow mounting zFS
file systems contained in multi-file system aggregates that are to
be shared across systems in a sysplex. IBM has previously
recommended that these multi-file system aggregates not be shared in
a sysplex environment. Once this support has been removed, attempts
to mount zFS file systems contained in multi-file system aggregates
will fail in a z/OS UNIX shared file system environment. Mounting
zFS compatibility mode aggregates, which have a single file system
per data set, will continue to be supported in all environments.
And:
In a future release, IBM plans to withdraw support for zFS
multi-file system aggregates. When this support is withdrawn, only
zFS compatibility mode aggregates will be supported. (A zFS
compatibility mode aggregate has a single file system per data set.)
See: http://www-03.ibm.com/servers/eserver/zseries/zos/zos_sods.html
for all the statements of direction.
