One of the biggest things they're doing is regression tests on the whole system. Solaris is used in many places, and they need to guarantee that the software is going to work. From the quality assurance point of view, in terms of the solidity of Gnome, it's a very good thing to have someone like Sun contributing that effort. The same thing happens with different companies. All of those companies are working together towards the same goal, some with different priorities than others.
Different people contribute in their different areas of expertise.
And the same is true with Compaq. Compaq is interested in the handheld market. H-P is also interested in replacing CDE, and so on. The foundation was something we needed. When companies became interested in the past, it was difficult to get the companies to grow with the community.
