With users changing from time to time, it's not really an option.
Besides, it's an embedded system, I would rather use the RAM for 
something else...

I did, but it just doesn't work:

root# lzo_fs -s -o allow_other,default_permissions /mnt/3
root# cd /mnt/3
root# mkdir users
root# chmod 777 users
root# su tch
tch$ cd users
tch$ copy /bin/bash .
tch$ ls -l
-rwxr-xr-x  1 root root 749404 Jan 27 13:53 bash*

The file is owned by root, although I would like it to be owned by "tch" 
user.

This one I didn't understand.
Perhaps you mean changing that in LZOlayer_fs sources?
BTW, I didn't write the filesystem, I merely used it.
