QT on Win: possible deal-breaker, need alternative

I have a project out to bid which is currently spec'd to require 
QuickTime on both Mac and Win.  The client is discussing this with his 
customers to determine whether it will be acceptable to them to install 
QT on their systems.  In the event that those customers say no I need a 
backup, and preferably one which lets me deliver this project in Rev.

Here are the specs:

a. Source media files are in WAV, AIF, and MP3, with thousands of them 
and many of full-length songs so embedded audio clips are not an option.

b. Must be able to play the file.

c. Must be able to move the playhead in whatever UI we deliver to allow 
playback from arbitrary starting points.


In my tests here using a Win XP system without QT installed, b. works 
fine only for MP3, but I couldn't play WAV files in Rev at all.

c. was a non-starter for all formats: attempting to set the currentTime 
for a player control yielded no change to when the file began playing; 
if the file had not be played before it would only play from 0, and if 
it had played and been stopped using the stop command then the next play 
would always resume where it had last stopped, regardless of the 
currentTime.

Last time I asked about this here one of the responses (from Andre?) 
suggested using a player made with Flash embedded in HTML inside the Rev 
browser.

If we have no alternative that may be okay, but I'm concerned about the 
layers of overhead introduced by relying on those two extra components.

Have any of you used a similar configuration for playing WAV files on a PC?

Was the performance acceptable?

Any drawbacks with such a setup?
