For uploaded non-image media (usually .ogg at the moment), how about an additional, automatically generated link like
<a href="#" onClick="self.location='foobar.ogg';return false">Play</a>
For our current link, I always get the open/save dialog, which *can* be great to store the file. But to listen to, e.g., a pronounciation ogg, quick'n'dirty in-browser playing would be nice too.
And, no disadvantages for the tin foil hat^W^W^W^W our JavaScript-disabeled friends :-)
