AIR encrypted loopback filesystems require a pass-phrase in order to mount
(i.e. it is unlocked when you mount it - not something you would want to
happen un-attended).

Inidividual files can be encrypted using pgp or ssl, and the unix filesystem
and security model can be applied to most cases without resorting to ACLs
(I HATE ACLS!). If allowing un-attended reboots is a must then I suspect
this maybe more apposite to your application than an entire encrypted
filesystem.

Regarding speed - an encrypted filesystem will be slower if you do it in
software - whether the effect will be significant / noticable....we'd need
to know a lot more about the application / hardware / i/o traffic to hazard
a guess.

What NTFS encryption?
