I don't know exactly how you pass data among nodes, but wouldn't it
possible to pass pages in compressed cache in the compressed format,
without decompressing them? In this case, it would have to be added to
the compressed cache in the target node, or decompressed if the cc
does not accept it for whatever reason or even if the system doesn't
have a cc. In the latter scenario, the om should be aware that the
data might be received compressed. (I hope this email makes any sense
:-).
