Not sure how Marc does it, but on the machines I support that
are running CMUCL-based application servers (behind Apache), the
application server has a REPL listener pending on a Unix-domain
socket (a.k.a. local-domain a.k.a. AF_POSIX). Then I just SSH to
the server host, and once there I Telnet to the REPL socket,
which is protected by both filesystem permissions and a password.
Then I can look at stats, LOAD new versions of functions, etc.
 Recent BSD-derived "Telnet" supports connecting to Unix-domain
sockets ["telnet /foo/bar"], though Linux doesn't seem to have
picked that up yet. On Linux servers I just use Dan Barlow's
"detachtty/attachtty" on the actual top-level REPL. Same thing.
