I have done something a little like this. In our case we have an
internal web application and I needed to be able to include graph images
in that web application that are derived from RRDs.

I set up Apache on my Linux host that generates the RRDs (using MRTG)
and developed a fairly simple mod_perl application that takes a request
with various parameters, it then uses those parameters to find the
correct RRD and generate a graph image, which it then returns to the client.

So, then in the web application I just put <img src="..."> tags at the
right place with the src="..." filled out with the right request. When
the web browser processes this tag it makes a request to the mod_perl
server and gets that image from there.

Not sure if this works in your situation, but it sounded close enough
that I would share my solution.
