  Actually, yes... At first everything seemed fine but I've been getting 
quite a few reports of major problems... The application (EchoMac) 
seems to work fine, but after they quit the program it messes up audio 
for everything else and many applications crash...

  Here was a dump from a crash of iChat after having run my EchoMac 
program.... Note the errors when it's trying to do audio stuff:

Thread 6 Crashed:

  In fact, he did a reboot and iChat still crashed when it tried to 
first play a sound. He claims he cannot even get iChatAV to run now, it 
crashes whenever it tries to play a sound.
