IIRC correctly there's being developed file event mechanism - more
general which should work with other file systems too. I have no idea
of its status or if someone even started coding it.
Your second question - no, you can't.
Yes you can and it has been there even before ZFS existed see fsattr(5)
it isn't ZFS specific but a generic attribute extension to the
filesystems, currently supported by ufs, nfs, zfs, tmpfs.
apparently fsattr is not part of OpenSolaris or at least I can't find
it..
oh, this is API...
the (5) is a section 5 man page, which is the misc dumping ground for
man pages.
If you want a CLI interface to this see runat(1), for example to create
an attribute called mime-type with the content 'text/plain' on file foo
you could do this:
$ runat foo 'echo text/plain > mime-type'
To see the value of mime-type for file foo do this:
$ runat foo cat mime-type
text/plain
