This is slightly off topic, as it isn't a kernel implementation. But in regards to encryption options above the filesystem, there are user-space tools for doing this.
For example (ahem, shamelessly plugging my own work) pobox.com/~vgough/encfs.html - an encrypted filesystem in user-space which uses the Linux kernel module FUSE (sf.net/projects/avf) to export a filesystem interface to userland. As a side note, FUSE also has python, perl, and Java bindings for your programming pleasure.
EncFS acts as a pass-thru layer to an existing filesystem, so it does not require allocating space ahead of time. But it does not do what the original email asked, of encrypting on a file by file basis. It is more like a reimplementation of CFS, but without NFS being involved. What was asked for sounds more like TCFS (for 2.0.x and 2.2.x kernels).
