As PodMaster says, you can't do this with a normal browser.

I have a vague recollection that some early versions of MSIE on the Mac did try to encode things in AppleDouble format if they found a resource fork - but this is certainly no longer true.

If you want to keep everything as a web service, you could write a perl script for your Mac users to run locally that packaged up the file in an appropriate format, then use LWP and friends to POST it to your server. MacPerl works very well on OS 9, and you have perl as standard on OS X.
