Development Immortality

Development Immortality (DI) refers to a project, which once seeded, never dies out in terms of continued development on the project. This means that sufficient assets are available for future development to continue, for ever, improving the product until release.

There is also a subtle distinction with a project like GNU HURD, which apparently never dies, but which also apparently never moves forward in a significant way. As such, HURD is not specifically attaining DI, but more like attaining the status of the living dead, where the odds of product release do not increase with time.
