How can you make a recursive symlink for folders/files in Ubuntu?

My folder Structure

/UNIX
    /Find
    /Grep
    /Find-Grep

I made a symlink to the UNIX folders unsuccessfully by

ln -s /I/Unix path/Dropbox/myFriend

I removed a .todo -file at /Dropbox/myFriend/Unix/Find/.todo. I noticed that that my .todo file at /I/Unix/Find was also removed.

How can you make a symlink such that my friend can see my files but he cannot remove my them in my computer?

[edit]

The first problem is solved: we can create a recursive symlink.

However, we have not found a method not to allow my friend to delete my files in my computer too, when we use Symlinks in Dropbox.

I was going to suggest remounting the directory bind,ro

mount -o bind,ro /I/Unix /Dropbox/myFriend

but it seems that functionality isn't in the kernel yet. Might be in yours, but not in my ubuntu box. So, alternately (instead of changing the permissions on all of your files) you could export the directory to nfs as read-only.

Change the permissions on the file/s so that he does not have group, or other, write access.

You could do:

chmod g-w,o-w -R /I/UNIX/

crb@server ~ $ ls -l test/dir
total 0
-rwxrwxrwx 1 crb crb 0 2009-04-14 10:35 example-file
crb@server ~ $ chmod g-w,o-w -R test/dir
crb@server ~ $ ls -l test/dir
total 0
-rwxr-xr-x 1 crb crb 0 2009-04-14 10:35 example-file
