[R] cgi/servlets/httpd in R

[foobar]

Hi R-helpers

Has anyone had any experience doing CGI or Servlets or using an httpd 
server in R?

Context:  we are interested in running dynamic demographic calculations 
on the internet (life tables, and such) in response to form submissions. 
  I might do simple cgi to get started, but loading in data each time 
seems like it would be quite, quite slow.

I have looked at Rserv, but I am most interested in something non-Java 
(once Sun goes the way of the dinosaurs, so will that silly language -- 
come on, flame me, I can take it!)

If there is a project, I might be able to contribute to it.  If there 
isn't, I might start one....

Thanks!
