Does anybody have a currently working solution for some kind
of encrypted filesystem on NetBSD?

I'm looking for something like cfs (which I've used under
linux before) -- when not 'mounted', the files aren't stored
anywhere unencrypted.  I've investigated a few solutions
without much success (like tcfs, which I notice had a new
release in January, but still only ports to NetBSD 1.4.2).
A slow and hackish solution involving GnuPG and the risk of
both data loss and unencrypted data in swap space would be
easy to implement, I suppose, but something a bit more
efficient would be nice.
