[gst-devel] mixing "beeps" in with the main audio stream

I am trying to determine the best way to mix short "beep" type sounds 
with an ongoing stream. These beeps will be for notifications while an 
MP3, OGG, etc. track is playing. I'll be using gstreamer as the media 
framework for an appliance-type media player. For instance, click the 
"up" button on the control, hear a "bloop" noise. Think "TiVo."

ShouldI make two piplelines, one for the beeps and one for the main 
audio stream, and then mix them together and send it to oss? One 
pipeline with several bins? Should these be separate threads? Would I 
need to modify the running pipeline to play the extra beep sound?
