Right, that's what I'll be using in the future (when our new linux server
arrives). I will be using mod-perl for generating labels from forms input. I
am not sure if context is the path for our company, since what we need is
pretty trivial, and can easily be made using pdflib. On the other hand, I
can easily use plain pdftex, since this generates pdf files at high speed.

Taco's solution is very promising for the web-server approach. one can
easily obtain a unique client id, and run the stuff in different
directories, based on that id.
