Well, CL could distribute the manual within an exe loader that searches your hard drive for a legit copy of P4 or PPP and then ask for your registered serial number to unlock it. Or, since all of us have registered copies, just send the manual if we respond in an email with our serial number in the subject line. There are a lot of vendors out there who will send you to a protected, password-locked site to download the product you purchased. I just purchased IFW2 textures for Mac LW7.5 from Richard Jennings and that's what happened. Another instance was when I beta-tested Ozone 2 for e-on software for LightWave. I was given a secure site to download the product, but I had to give them my hardware lock to obtain a serial number to install and use the plug-in. Just my $.02US - now back to my hole under Middle Earth for a while...
