A tool for distributed software development maintains a pool of software modules. A module manager manages submissions to and downloads from the pool. The module manager can be a computer system with programming and resources suited for managing the pool. Developers and users can access the module manager via a computer network such as the internet, or via other transmission mechanisms. A developer intending to submit a module to the pool can specify access conditions associated with the module, and transmit information needed to access the module. The module manager can add the access information and access conditions to the pool. A developer or user intending to access a module from the pool can identify a desired module. The module manager can then determine if the intended access complies with the access conditions associated with the desired module. If it does, then the module manager can transmit the access information.
