Small Programmable Object Technology (SPOT) is part of the J2ME family and aims to allow developers to build programs for wireless sensors. Sun are releasing a developer kit which will consist of two wireless sensors, a base station and the JavaBeans development software all for $499.
The aim is to allow researchers and budding hobbyists to experiment with the kit and see what type of systems it can create. Not sure if I am that interested in that area but I’m sure there are plenty of people that will be interested. I’m look forward to see what type of applications will be developed.
