Almost by definition, appliances are useful, cost-effective devices or tools. This holds true for smart' appliances as well-they must provide a reasonable level of computational and communications capability and be interoperable with other devices in their environment. The issues around interoperability are best solved via standards-based connectivity and communications protocols, such as Jini, OSGi, UPnP, and others. However, in the case of Jini, the static and runtime storage requirements of typical implementations are too great to be considered for the embedded systems in appliances. PsiNaptic has developed a version of Jini that is compliant with the Jini specification and requires an order of magnitude less storage than the reference implementation from Sun Microsystems Inc.
