I am working it up as we speak. As for the issue you present here... The key is to remember that .htaccess is primarily designed to protect directory contents. Files in the same directory are difficult (not impossible) to protect using .htaccess.
The second example works but ONLY if you have another .htaccess file in the "/other/" directory. That .htaccess file should contain the line:
RewriteEngine off
...for maximum compatibility with scripts and such.
Hope that helps,
