Dealing with delay between playbacks

If you listen to the same stream on computers in multiple rooms, they are all at different places in the stream, which results in an incredible, unpleasant cacophony. If you change to vlc streaming from one and listening to the stream on the others, the result will be that all the others are at different delays from the stream server. Here's what to do to address this issue:

1. 
   On the streaming vlc server: Do not check the "display locally" box. It will stay silent, you will not hear anything, however, the stream is sent out.
2. 
   On the listening VLCs: Tighten the buffering/caching: Start with a 20ms caching and increment by 10 until the stream is free of cutting out. In the startup phase it will always cut out a lot, but the stream will stabilize after about 5 to 10 seconds and be smooth.
3. 
   To listen on your sending computer: Open a second vlc client and listen to the stream as you do on all the others, same caching/buffering values.
4. 
   Note that all caching values seem to need to be the same.
