no doubt they could edit the data to remove their name before passing it on...
I could as they do - watermark on PDF, but my model is to make the data more accessible/usable and in doing so I am making it easier to freeload, hence why I am trying to make it cheap enough that users would just sign up and pay the monthly fee and get the benefits of some customization, rather than freeload.
Also the real money isn't in the data it's in other things, but I need the audience so I'm going to offer it really cheap, get the audience, get them famliar with the software then sell modules (the real pot of gold). I could jut get it out there for free, but I need to learn this pricing/billing stuff.
That all sounds good, my only thought is if you are charging $5 for something your market is used to paying $600 for, you may appear to lack credibility... imagine going up to a guy who gets $100 haircuts and offering him a haircut for $3. Would he take the risk of getting a $3 haircut, even if it looks like it would be just as good as his usual $100 one? But, of course, if they're getting other stuff than just the data for the $600, offering just the data for $5 plus expensive modules might be perfect ^_^
