1. amazon s3 theft prevention - lock your amazon content so everyone can view it on your site / paid pages, but can't steal it and use it somewhere else.
2. exit pop - dead-simple exit pop on any page/post you want it on.
3. delayed "add to cart" button - dead simple way to "hide" your "add to cart" button and have it appear when you want it to (great for video sales pages, makes them watch X minutes before being able to see the price)
I've seen a number of php encryption softwares available, I obviously want to stay away from any that require server modifications.
One in particular I'm looking at is phpcipher. It says that most servers already come with the modules needed (zend optimizer).
Looks like the next best thing would be an obfuscator, but it doesn't really lock down the code...
You guys have any experience or recommendations?
