Linux ZFS is still quite young, only supports a very early version of the fs, and can't be updated to the newest without serious reverse-engineering.
As for ZFS on windows, I definitely would not hold my breath.
I ran into the same frustration as the author and gave up. My notebook triple-boots Linux, Solaris 11, and OS X (I have no use for windows) and would be beyond thrilled to have ZFS shared among them.
One other problem with the idea though... you'd have to export the shared fs each time you shut down and import it into the next OS you booted, which would be kind of a pain (of course you could force the imports, but that's ugly and it only saves one step).

They no longer list the versions on the front page.
Last I saw the page was only a few months ago (max) and you couldn't even create a filesystem yet (you could create a zpool and zvols).
I remember reading on that page the zpool and zfs versions implemented at that time, and they were way back.
And yes, I am using Solaris for comparison... I mentioned that I'm triple-booting with Solaris in the post you replied to.
I'm glad so see the development has caught up, but it is still quite young.
