encrypted filesystem

Hello, I've been keeping my ears and eyes open in the BSD world for a couple 
years looking for encrypted filesystems. Rubberhose's features look nice, but 
it doesn't build on netbsd, and hasn't been developed in a couple years. TCFS 
did compile, I've got it to build in a netbsd-1.4 chroot with -static and the 
programs seem to run fine. I dont know C very well but it looks like the 
grammar has changed in netbsd since the tcfs release in 2000, meaning I 
havn't got the -current kernel to use the tcfs file-system.
CGD isn't quite what Im looking for. Files are not protected from root, or 
anyone else while its mounted. CGD is fine for swap though.
When tcfs works (3 years ago), it can be used with vnconfig to encrypt 
filenames, aswell kerberos can be intergrated for network password database 
sharing. /tmp files can be encrypted on a user by user basis. This package 
has a lot of potential.
Are there any encrypted filesystem for bsd that are multiuser, other then 
tcfs. If not is anyone interested in helping me bring tcfs back to life?
I noticed openbsd's copy of tcfs has copyright violations, which is why they 
dropped it. The netbsd version doesn't share those copyright issues. v2.0 of 
tcfs has a COPYING file which is gnu/gpl, and therefore any version derived 
from it would also be gpl, with the exception of code clearly marked as 
having a bsd license. I have emailed every tcfs address I could find with no 
reply, I think this was a school project, and the students finished school 
and forgot about it.
So, does anyone know of a better encrypted fs project, or, again, would anyone 
like to join me to help make tcfs work again.
Best regards
Robert
