No problem with Nginx, it can buffer on a temp file (and you can force 
it to *always* buffer to a temp file), so you can just run the XSLT 
processor as a separate process and send the resulting file to the 
client (perhaps using sendfile).

Unfortunately Nginx does not offer an infrastructure for process 
handling to be used by modules.
