zfs porting roadmap?

[Lukas Rössler]

I browsed through the archives of the past few months and saw that zfs 
is already ported up to v28 atm (thanks a lot at pjd - you do awesome 
work!).

Don't get me wrong here, i don't want to sound demanding in any way, i'm 
just interested - are there plans to port it up to the current version 
(31, i believe)? The killer feature for me is encryption, which was 
added in v30...

Thanks again for all your efforts, and thank you in advance for 
answering a noobs question :)
