I haven't but I just did on a HDD, makes no significant difference that 
I can tell.

Yeah. Overall I believe the transition to SquashFS for the rootfs would 
be good for size definitely.
On CD media alone probably speed too, though with DVD media I'm almost 
positive it would be
something outrageous. DVD reads are fast anyways.

Another thing I was seeing a few weeks ago was the optimized cloop 
filesystem used on Librenix, I think it was.
I've been told on some CDs made with Kadischi booting the CD sounds like 
a bag of nails.
Hah!
