Plus.... if you're getting so many images with red eye that you need something that can batch process them, then can I suggest you need to be looking at your lighting techniques to solve this problem, not processing?
If you're removing it from old images... just do it manually. Doesn't take long.
I downloaded that t test it. When it works, it works well, but it misses a great many if there are multiple people with red eye in the shot.
It got the kid's eyes in this one....

So if you can't trust it, you'll just end up manually going through them all again anyway.
You can't load a file into it, which is annoying. It ONLY works by searching a folder, which means in order to batch, you need copies of al the suspect files in a folder... very annoying.
I've un-installed it. It takes 10 seconds to remove red eye from a snapshot.
