My understanding is:
There's a DTrace beta for Linux. There are no plans to port ZFS to Linux (but, Oracle is investing a lot in making btrfs kick ass).
I'm not looking for a 'kick ass' file system... ZFS does have some features I am interested in though, and I would appreciate having it made available to me somehow.
I was going to leave you alone about the 'messaging' aspects of your post, but now I'll point out that your reply exhibits a similar tone.
