Programs: Lock up your servers against Fusker

[raymor]

I've designed what should be a reasonably good solution
for this. It'd secure your images and shouldn't block anyone,
no matter if they have they block the referer or not.
It's a couple of scripts and a bit of creative .htaccess that
I'd need to just code up real quick if there's enough interest.
I'd sell my script installed and tested, sold per domain.
In order that I might know if this would be worth my while
to code up, test, and let people know about, what do you
guys and gals think would be a fair price for it that you'd
be willing to pay?
