Exact, you can do it using the stream output of VLC.

The synchro problem is the same with the DivX file and a MPEG2-TS 
stream. Both video and audio have timestamps in order to know when to 
give the frames to the outputs. So when you convert your file to 
MPEG2-TS, timestamp are added to each of the elementary streams.

The two differences when you stream are:
1. you may not have the beginning reference, but as timestamp are
    repeted in each frame, it is not a problem.
2. you don't control the reading speed, so if you have to adjust your
    synchro, you will need to add a buffer somewhere in the decoding
    process.

Does that answer your question ?
