I couldn't agree more Joel.
People think that the prevailing model will be similar to a retail model. For example, LayerByLayer wants you to pay for each and every print that you make.

At https://3Dagogo.com, we feel that the prevailing distribution model will be more similar to the music file distribution model. You pay for the license to play the music file, then you can keep playing it over and over without repurchasing. However, if you use it for business or commercial ventures, you have to buy a different license.

At the same time, DRM will be moot (just like in the music industry) if the designs are priced low enough. $2-10 design files will likely not be pirated, however if you ask for $10 per print, it probably will be pirated.
