Comment(by nitin):

 Replying to [comment:8 bluefoxicy]:
 > Nitin seems to have moved on to aiming for the embedded field, while the
 XO more closely relates to the desktop field.  I am not sure the real
 impact of this change, but the project here will be slow unless someone
 knowledgeable about the kernel's memory systems gets together with him.

 The only difference in new development is that we no longer compress page-
 cache (filesystem backed) pages since reading from flash is fast. Since XO
 is also using flash for storage (I think), so this is applicable here
 also.

 With this change, the code is significantly simplified and requires no
 kernel patching at all - hence more likely to go mainline.

 FYI, new dev home: http://code.google.com/p/ccache/

 > Another person has started ANOTHER memory compression project as part of
 Google's Summer of Code 2008 now.  http://code.google.com/p/cclinux/

 I have talked to the developer of this project and it seems only purpose
 here is to learn Linux VM. We are also planning to merge these efforts
 later.
