If you would integrate it into Open Solaris then every time anyone
change something he/she has to make sure nothing else breaks.
Now when it comes to CAS - I belive that instead being block
based it would be much better to actually be file lever aware and then
to understand (plugins?) different file formats - that way I belive
you could achieve much better efficiency.
