"It's a concern" that Sun chose to adopt NeXT's technology, said Larry Loucks, vice-president of software architecture with IBM's personal software products group. Industry insiders and other COSE founding members wonder where Sun's loyalty lies; IBM and Hewlett-Packard, for example, have committed to using competing Taligent technology.
But according to Jim Green, SunSoft's director of object products, "COSE agrees that all vendors will build on [CORBA] technology," adding that each vendor is pursuing different avenues to build the best object-oriented development environment.
