Autorun of PP downloaded from web.

I have authored a presentation that I had hoped to deliver as a web
app, but when I test it in various environments, some of the
animations break (ironically IE6/XP seems to be the most
unpredictable.).

As plan B, I'm looking for a way to allow download of the
presentation, but it needs to essentially "autorun" when downloaded.
I looked at pack and go, but requires recipient to have an unused
directory, execute the unpack program, know where they put the
resulting files, go there and launch the PP. This is too complicated
for my intended audience.

Any suggestions? Tx.
