Hi,I've seen what monster size a 500-article PDF can have (in excess of a
1000 pages and 140MB of data), so maybe an other kind of solution would be
advisable:
- either possibly give e.g. sysops the right to create collections that are
over 500 pages (for legitimate books with more articles), that can be
downloaded by anyone: having saved collections would mean that all these
large collections can be safely cached
- other nice idea would be to try to calculate the size (in pages and
megabytes) of the book if it has more than say a 100 wiki pages, and before
going into the CPU intensive layouting/rendering phase display a warning
that

"Your book is going to be approximately 1234 pages long, with pictures that
is about 435 MB on a 2MB/s internet having a download time of 40 minutes and
the rendering time with current server configurations will take 35 minutes.
Do you want to go ahead?"  - or something less scary, but to the same
effect. Last time I tried a 140 MB PDF I was frankly praying for my computer
not to crash due to not enough memory...

Best regards,
Bence Damokos
