There has been some work done by John Lapeyre on using R as the
backend for the perl data language (pdl).  I believe he was not
working through sockets or anything like that.  He was using the R
source code.

 Package: r-pdl
 Section: math
 Installed-Size: 982
 Maintainer: John Lapeyre <lapeyre at physics.arizona.edu>
 Version: 0.2-2
 Depends: pdl
 Description: 'R' statistics for the perl data language
  r-pdl is an interface to a  collection of about
  100 routines from the R statistics language, for pdl,
  the perl data language.  The routines give information
  and random deviates from common distributions used in
  statistics.  Provisions for a user defined random
  number generator have been added to the original R
  code.

You can get the source code for this off any Debian GNU/Linux archive,
such as ftp.debian.org.  From the top of the archive the path will
look like debian/dists/slink/main/source/math/r-pdl_0.2-2.tar.gz

Recently Thomas Lumley announced a sockets library for R.  I'm not
sure if that allows R to act as a server.  Perhaps Thomas can comment.

Another, related project called omega (http://omega.stat.wisc.edu/) is
just underway.  A goal of that project is to provide distributed
statistical computing through CORBA modules.
