Is there a Linux "file-safe" for Fedora's home file..?

That would be the way, but it creates something of a partitioning
problem, both in that it doesn't scale and that if your system is
already partitioned you can't do it at that point.

But using the same general idea one could make a sparse filesystem image:
make a nice big sparse file, attach it as an encrypted partition (I'm
imagining LVM and/or dm is the right tool), mkfs, mount.

Someone who knows the commands to make an encrypte filesystem and to use
LVM or the device mapper stuff to map a file to a mountable device
should be able to fill in the gaps.

That should get you I/O behavour much more efficient that FUSE based
methods.
