In the past, embedded operating systems have been priced to sell in OECD markets. The Unison Stellaris offering has world pricing. It is a cost effective approach in the lowest cost venues in the world as well as the most expensive venues. This opens the door for users in OECD countries to get a superior offering for a fraction of the traditional prices for substitute products and allows developers in other countries to use the very best and most reliabile software offerings at prices they can afford and that make sense given their economics.

Future components under version 5 of Unison are planned. These components are expected to provide the following features: motor control, CAN, USB, Diagnostics and motion control.

Unison is a fully POSIX and Linux compliant OS with the ability to easily port applications from Linux and other POSIX environments to it. It has all the necessary features to provide support for the following applications:

• Advanced connectivity and networking
• Wireless sensor networks
• Appliances
• Home automation
• Clean tech and Smart Grid components
• Automobile and vehicle automation
• and much more
