I have the same plans, though it is a linuxkernel course. My plan was to
make a combination of LVM2 and PPDD (encryption). The idea was to make 
LVM support encrypted LV's that would need to be unlocked before usage,
in order to make blockencryption easier. 

LVM ontop of loopback encryption wont work, as i then need to encrypt
hole LVM, and some files are not sensitive.

loopback encryption ontop of LVM wont work, as the live snapshot feature
then doesnt work.

I had the idea to make it possible to encrypt the LE (Logical Extends)
that the LV was encrypted, because it would seem the most aprociate
(i havent actualy read the LVM code yet, just the documentation and just
for LVM1.)
