[Bit OT]: Latex Gurus?

["Byron Hillis" <b_hillis@optusnet.com.au>]

Hi all,

Just wanting to tap into some of the wide-ranging knowledge
available on this list.

A quick Q for a Latex document layout. I want a single 
column output, but on the right hand side I want a line 
that separates the \marginpar notes from the rest of the
text. Like this....

      Body Text Body Text Body Text |
      Body Text Body Text Body Text |
      Body Text Body Text Body Text | MarginPar
      Body Text Body Text Body Text |

I've googled like hell, but I'm not sure exactly what
I'm looking for. I want it on every page, so a picture
environment doesn't seem to be an option (but I could be 
wrong). I was thinking maybe an image placed behind the
text with the line in the correct location, like a 
watermark, and that lead me to find the eso-pic package,
but I couldn't get it to Compile when I used the
\AddToPictureShipout command. 

I'm using PDFLatex to compile, on Sarge with a complete
Tetex install.

Thanks a lot for your time,

Byron
