Already done for ftp and http and some others.. Look at userfs and autofs.

Already done with the loopback device - which lets you mount a filesystem
image living in a regular file. The encryption is either weak or dog slow,
unless you have a bunch of CPU, but not - AFAIK - needlessly so.

When I compile kernels I always compile lots of filesystems in as modules.
Then I can use 'insmod' and 'rmmod' to do just this.
