Is there any way to do software RAID-1 not with hard drives but with truecrypt volumes after they are mounted? Maybe with alternatives to truecrypt like bestcrypt or others? One thought is to use virtualization whereby the two mounted truecrypt volumes will hold the two virtual disk images of a VM that does software RAID-1 between its two virtual disks. This is trivial to set up but it's got one drawback: you cannot run VM's inside the resulting VM at full performance, as the host VM would have to have VT-x disabled. Any other ways? Target O/S is Windows 8.1.
