Windigo - 
    Loved the episode. Very well articulated! I had one thought. When you want to run your prompt as another user (or, have other-user specific prompts), you don't need to do any symlinking, especially on a multi-user system. 

For example, on servers I helped manage, I had .rootbashrc in my home directory, and after I did a sudo su - to get a root shell, I would then source /home/x1101/.rootbashrc to get _my_ root specific rc file.

Just some food for thought.
