Hi, and thanks for the responses. I had actually stumbled across the referenced script in my initial search of hotscripts. Hotscripts tends to be hit-or-miss, and this time they were a miss.
If nothing else, I might just hack something together in PHP.
As for being paranoid, I have thought about it and I've decided it is worth it. Most of the people I want to share these files with are not particularly tech-savvy and in this case an ounce of prevention will go a long way, and in the long run it will probably be worth it to me. As much as I sympathize with information wanting to be free, my rent, food, student loans, bills, and web hosting are not, and so my time and energy aren't either.
