A computation can create new computations dynamically. Computations can roam the shared Mozart space at will. Each site has full control over what resources it makes available to incoming computations. The Oz virtual machine is portable and known to run on most flavors of Unix as well as on Windows. The Mozart system was designed to be easily extended with new native functionality packaged as DLLs.
Comprehensive support is provided for the convenient creation of DLLs.
Thus, the Mozart system is not only aggressively open, but also an ideal very high-level glue language.
