Dear William,

I think it is not that hard. We have (actually, Juanma Vaquerizas has) 
prepared a cgi that works as a web interface to limma and a few kluges of us; 
you can give it a try at http://dnmad.bioinfo.cnio.es.

The basic skeleton is Perl, and we we use the CGIwithR package 
(http://cran.r-project.org/src/contrib/PACKAGES.html#CGIwithR), by David 
Firth, to communicate between R and Perl; figures are displayed as png (we 
are satisfied with the png's quality). We also tried RSessionDA (see Greg's 
message), but we had a harder time getting it to work, so we opted for the 
solution above.

Please note that this is just a beta version! (and it is running from a dual 
Xeon machine, so please, be gentle). If you can wait a little bit, we are 
writing a note for R news, and we will provide all details there, and 
downloadable code from our webpages.
