I'm also in need for such functionality, the only difference is that i need 
for both channels to hear the message. As i have read press releases, there 
will be something similar available in 1.6. If you succeed, please give us a 
note - how it can be done.

Well, you can create conference dynamically whenever you need to play the 
file. I started working on this, and have found several bugs regarding this, 
but they should be fixed in 1.4.12

Idea is to Redirect() trough AMI both channels to dynamical conference, and 
then attach call with Playback() to the same conference. For now, the 
Redirect() part is working fine, but due to lack of time, i haven't got 
further.

My collegues tried this but unsuccessfully. The basic idea is to use local 
channels - one is bridged to Chanspy() and second to Playback(). I'm not sure 
what is the problem, but theoretically also this should work.
