[plt-scheme] running web-server on port 80 as non-root?

I've been running my PLT web server as root, in order to use port 80,
on Debian Linux.  It occurs to me that maybe I don't want to be doing
this...  Apache has the "User" directive that does a setuid after
binding the listener port.  Can MzScheme do setuid?  Or should I just
write a simple port-forwarder?  Or, is there a way to tell Debian to
allow a non-root user to use port 80?
