You can try context --pipe --result=/tmp/result.pdf but that only runs the 
document once, so cross referencings, TOC, etc won't work correctly. The 
other options is to write to a file, and then run "context --purgeall 
--result=/tmp/result.pdf filename"; this will run the document appropriate 
number of times, and then delete the temp files, leaving only the .tex and 
the .pdf file.
