Is there any way to load a local file (or even an URL) with ConTeXt? How should I rewrite the following command to load a local file or an URL in ConteXt live?

Live doesn't allow you to load local files. People could upload all kinds of junk.

Actually I wanted to get proper imposition for “The Future of The Internet — And How to Stop It” on a computer that doesn't have ConTeXt installed and on which I couldn't install ConTeXt even if I had administrator rights. Sorry, but I don't understand the problem here. If people upload all kinds of junk, why is this an issue? Or does ConteXt live show or store data for other users than the uploader? I thought that it was not a hosting or publishing service. Thanks for your help, Pablo
