To actually manage the RAQ you use the Web management screens. To manage a group of RAQs, you can download special software from Cobalt. Cobalt won't help you there. Why did Cobalt decide to use a MIPS processor rather than the standard chips most company's use. I don't know.
Intel chips are pretty expensive.
The Qube and RAQ are very good at pumping out static pages. You can probably serve millions a day. They're not so good at dynamic pages. See the Zope section for details. They plan to use the AMD chips from now on.
