We have developed a distributed computational infrastructure using R  
(and JRI) as the backend coupled with AXIS web services and have  
built a number of clients on top of this.

You can browse the source code for the services from the Sourceforge  
repository located at
http://svn.sourceforge.net/viewvc/cicc-grid/cicc-grid/rws/trunk/  
(though the R code in the repository has not been updated recently)

Examples of what functionality is available via the web services can  
be found at http://www.chembiogrid.org/projects/proj_statistics.html

The page also lists a number of clients that make use of the web  
service infrastructure.
