You can play SHN files directly from Windows Media Player if you install a DirectShow filter.
There used to be a download available from
http://www.rit.edu/~cxp6014/ but the site seems to be down at the moment.
Using the 'Way Back Machine' I was able to find a cache of the site and the installer can be downloaded from here:

I downloaded it last night and works great with Windows Media Player 11.
