I still went ahead and checked Kadow's Internet Dictionary (
http://www.msg.net/kadow/answers/ ) and found nothing on either rcd or remote communication demon (or daemon).
I searched Red Hat and found nothing for rcd. I then searched from Red Hat (all linux sites) and it came back with this:
http://ibiblio.org/pub/Linux/utils/shell/rcd.readme
RCD stands for "R'alf Change Directory", a small program
with C source that compile under Linux.
More information can be found there if you care to look. Don't know if this will help you or not. Double check your sources to see if rcd really stands for remote communication daemon.
