The Chorus Object Oriented Layer (COOL) is a layer built above the Chorus micro-kernel designed to extend the micro-kernel abstractions with support for object oriented systems. COOL-02, the second iteration of this layer provides generic support for clusters objects, in a distributed virtual memory model. The authors discuss experiences with COOL-1 that have had to their current model and in particular, with their decision to build a two layer system where the lowest layer supports only clusters and the upper layers supports objects. They describe a number of problems that they are addressing with this new design and present the current status
