File upload conversion


  I was wondering if anyone has an written a rails app where users upload word documents and on the server convert that file to a pdf?

I'm trying to figure out the best way to convert the file to a pdf on the server. We are deploying our app on a linux web host (for cost reasons we are on a shared host) where we don't have open office in headless mode available.

I've been googling around and can't seem to find anything so I am kind of assuming my configuration doesn't support what I need my rails app to do but I thought I'd take a shot and see if anyone had any thoughts...
