The native version (built from the source) of the runtime environment (i.e., the Web broker) runs on most Linux platforms. It runs on Android and Maemo SmartPhones. It has been compiled for NASes (e.g., Synology DS-101) and some robotics appliances (e.g., Lincon i8000). The native version also runs on MacOS X. Other platforms should either resort on the Java port or the virtual image distribution.
