We are using ACL 4.3 for Linux in just this way (see
http://www.bbtech.com/http-inspector.html).  To start the
image at boot time, we put the invocation in /etc/rc.d/rc.local.
Be sure to run the image as nobody and worry about access
to the evaluator, etc, for security's sake.

It is possible to set up a server version of the Emacs interface.
Another approach is to use telnet with a port option to connect to
a special server that spawns a top-level loop when connected
(and authenticated).
