There is an iso, slightly mis-named, I think,
that seems to be the Adriane LiveCD English version:
ADRIANE-KNOPPIX_V6.4.4CD-2010-01-30-EN.iso 01-Feb-2011 03:00 698M

It includes LibreOffice 3.3, IceWeasel 3.6.13 & improved PCManFM initialization relative to 6.4.3.
Seems to give the same size persistent store (in round Mbs) as did 6.4.3.
Also gives uniquely painless Broadcom non-free wifi driver installation as did 6.4.3.
