Ubiquitous computing is increasingly becoming part of our lives. Various computing devices, having different sizes and capabilities, and using different software platforms are part of our working, leisure and living scenario, where mobile devices coexist and communicate with desktop and laptop computers. Because of this phenomenon, the need for reliable and efficient mechanisms to connect applications running on different platforms is increasing. In this paper we present a middleware which easies the process of development applications running in different platforms in a peer-to-peer computing environment. The papers also present the results of benchmarking tests and the experience of developing different applications with this platform.FONDECYT674FONDECYT
