*Well*, I maintain a set of crypto patches that are in production use at various places I've worked, *but* I've got the horrible disadvantage of living inside a country with draconian export laws.
Last time I brought this up & posted my "add-your-own-crypto" version of the patch, I got flamed and angrily told that there *was* an *official* kernel loopback/crypto patch, *much better* than mine and slated for inclusion in the kernel *Real Soon Now*. Needless to say, that was about a year ago.
Recently, I heard more rumor of an 'improved modular loop driver' that, also, was supposed to be integrated into the kernel Real Soon Now. Hmph.
In the meantime, the current loop driver has major SMP problem. I plan to address that in the next couple of weeks, and continue working on the assumption that all these New Better Drivers are vaporware, until I actually see patches available for testing.
Although the loop-driver is probably the fastest encrypted filesystem option at the moment, there are several other choices, most of which do some version of NFS loopback. TCFS and CFS are two that leap to mind: See http://tcfs.dia.unisa.it// and http://www.replay.com/redhat/cfs.html --Scott @ @ =-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-oOO-(_)-OOo-=-=-=-=-= C.
