I am currently working on this.  A re-write and merge of the Squashfs 
metadata and fragment cache code has been finished (it is in the 
Squashfs CVS tree).  The original implementation had a number of 
performance issues which I wanted to address before resubmission.

The major work of course is the move to a little endian layout without 
any bit fields in the structures to make it easier to swap member fields 
on big-endian architectures.  I'm currently working on this on a non-CVS 
branch.  Most of the work till now has been without any attempt to 
retain backwards compatibility with the current 3.3 little-endian 
filesystem layout.   After your private email regarding retaining 
backwards compatibility I will look again at this issue, it may well be 
that I will abandon my current layout changes that I have so far made.

I have taken time off work to work on the necessary mainline changes 
full time (unpaid unfortunately, so I need to look for another job 
soon).  Hopefully this will mean I will make better progress than I have 
been able to in the last couple of years.

Phillip
