Thank god, so this means we don't have to take any drastic and unpopular 
measures for now?
I think we should stimulate the P2P initiative some more. We need to 
make sure that a downloadable tarball exist for each book release. This 
contains all the packages one needs, patches and those rendered copies 
of the book, a list of MD5sums and the complete package digitally signed 
with GPG. This also needs to be available *before* the release so we can 
refer people to it in the announcement. I know Jeremy is helping with 
distributing; make sure other people with bandwidth share this package. 
Don't mention any http/ftp links so people will sooner install the 
necessary software.
Gerard, we really need to coordinate this effort a bit to make it work. 
There are people willing to share but if there aren't enough, 
downloading will be very slow and people will be disappointed.

I also inquired on a CSS-expert list about caching and forwarded the 
response to lfs-admin. It's a bit suspicious to me that these images and 
stylesheets get redownloaded needlessly every session.
Be sure to test with the default browser settings and an empty cache...
