Working with Rational Req Pro and their tools

At work we're trying to get Req Pro working. This is a great piece of software for managing requirments. As long as you don't have projects that interconnect. And you don't want to be able to search your entire company's requirements for data mining.
Here we are, in the middle of the IT world getting into the whole data mining, and the IT industry's so called premier tool can't do it. I get so tired of the cobblers children syndrome. We can't build cool software without tools, and if Rational is the best there is.... we're still buildling cottages and not skyscrapers.
