The most interesting to me specifically is the ability to define working copies through filter scripts. As far as I understand it, this is an alternative to branching. You can mix and match different components/alternative modules (e.g. different HALs or device drivers for different HW platforms) into sets of products without running afoul of the typical limitations of branches. However, Clearcase is just too expensive for us to even try it out seriously.
