Icecream was created by SUSE based on distcc. Like distcc, Icecream takes compile jobs from a (KDE) build and distributes it among remote machines allowing a parallel build. But unlike distcc, Icecream uses a central server that dynamically schedules the compile jobs to the fastest free server. This advantage pays off mostly for shared computers, if you're the only user on x machines, you have full control over them.
