I don't think the parallax in the mainline tree was ever developed very 
heavily; it seems likely that the version written up in the paper was based 
on a modified source tree.

But the code went unmaintained for some time and was presumably removed from 
the source tree due to it getting old and not working properly...  I agree it 
seemed like a really interesting technology and it's a shame not to see more 
done with it.  I get the impression that most enterprises are using NAS/SAN 
solutions already, so perhaps there wasn't sufficient demand for Parallax as 
a competing solution...

Cheers,
Mark
