content server on domain (internet)

Hi guys.

Hope some of you can give me some pointers on whether it is possible and if it is - how to do it.

I want to use Calibre a little alternative as a poster viewing system for a small conference. People submit abstracts and some end up during posters on these.

The format is typically PDF and I need a system where I can arrange these and where people can access them from their personal devices on http://conferencedomain.org/calibre

It's no problem to run this internally but the domain thing I can't figure out.

Any experience on this? Help is much appreciated. :o
