Facts from my point of view , OK fine, my opinions.

Knoppix cloop is compressed to a 100%:37% ratio. When making remastered CDs I typically see a compression rate of 37% or 38%. This means that a resulting KNOPPIX cloop of 695MB is close to 1850MB uncompressed. Based on the fact that mkisofs & ISO 9660 limits any single file in the filesystem to 2GB. So a KNOPPIX cloop file on a DVD is going to be at or just under 2GB. Assuming the compression rate is still around 37%, then Reverse the compression & it is roughly 5.5GB uncompressed. Still not enough for the whole Debian repository but that is simply HUGE compared to what a CD can hold.

I hope they have made 2GB DVD ISO image & not have made it bigger. I am gonna kick myself someday for saying this, but I think 5.5 uncompressed is enough for everyone.

I noticed the linked package list & I am impressed. Knoppix 4.0 will include both KDE 3.4.1 & GNOME 2.8.
