As I understand it, you are pretty safe. It's not *you* accessing the content.
The Tor guys recommend you have a web server on the machine which says "This is a Tor relay", presumably so that anyone who finds your machine during an investigation will know what is going on.
Two experiences of running a tor exit relay. One good, one less good:-

Good call. I was about to suggest this myself.
I have used MP3FS and it worked perfectly.
It's *the* ideal solution for people like me who like to have high quality audio on their computer but are limited to MP3 on their MP3 player.
I've got a bad feeling about this.
