(Nasdaq: SUNW - news) today announced it will rebrand its popular iPlanet, Forte, StarOffice and Chili!Soft product lines under the Sun Open Net Environment (SunONE) brand. This move reflects Sun's commitment to its wide array of software offerings -- spanning from portal server and middleware to directory solutions, developer tools and productivity suites -- that make up the Sun ONE platform for Services on Demand. Branding all of the products under the Sun ONE name will result in a singular focus that simplifies Sun's software portfolio for customers and streamlines marketing efforts.
