Single-system-image clustering delivers on that promise with no dependence on proprietary platforms. Linux is now slowly getting the underlying features needed to enable this (e.g. process migration and checkpointing, namespacing of all system resources), largely as a side-effect of earlier developments such as cgroups. You can already experiment with Linux-CRIU to see what the basic tech is like, it's not fully mainlined yet but it's slowly getting there.
