The idea of open source art is a key one to the art 2.0 movement. Google's Chrome operating system is a good example of open source in the tech world. The concept behind Chrome (every action on the computer interfacing with the "cloud") will also be important to internet artists.
The open source ideal is extremely contrary to what art has traditionally been: A Master creating his own proprietary work of self-reflexive genius. This makes it an incredibly interesting idea to think about.
