XSendfile

Hi all,

a friend of mine working with rails pointed me to XSendfile:

http://john.guen.in/past/2007/4/17/send_files_faster_with_xsendfile/

Now that some seasiders stated that they didn't know about it I wanted 
to ask on the Aida list as well if anybody has any experience with Aida 
and Apache XSendfile?
