With the Rational's CLM release this year, Rational ClearCase and Clearquest are now essential products in the CLM solution and integrate seamlessly with other Rational tools such as Rational Team Concert and Rational Quality Manager (eg https://jazz.net/library/video/597).
The session illustrated the new features in the 2 products as they make it into the CLM release. Its interesting to see how these CCM systems have evolved over time and now provide much greater flexibility with the open services integration of the Jazz platform. Jazz.net/library has really good articles about the new features. Also read https://jazz.net/library/article/550 for more info.
