You can stream your music wirelessly to your boombox. You just plug that into your boombox's audio input (if your boombox has one). I personally haven't tried it out, so i'm not sure how well it performs.

As been said, this doesn't require any special software, just your brother on his computer needs to share the music with you and you just can listen directly it from his computer.. thats what I do, my brother shares everything for me and I directly watch movies, listen to music from his hard drives and there are no problems, especially if both computers are running Windows, they have Samba by default, but as I am running Windows XP and Linux mostly, I have some issues.. my brothers computer is always running Linux, so he needs to install and turn on Samba service on his system that I could listen to music from his computer, but this is just because I could not make NFS work on my computer, when running Linux, this is even more simple and less resources hungry, because both computers on the Lan are just using NFS and can mount whatever you want in the fstab

The only issue, is to configure everything if there is more computers on the Lan and you don't want to share the stuff with them, this requires some more knowledge and not only several mouse clicks

Everything said is OK, but what if You want Synchronised play of some music on two or more computers? I think that there must be some streaming made.

If you run both pc's with windows, you can set up windows media player to watch network folders and use the other pcs music that way.

Just have to turn on file sharing, and configure your firewall (if you have one). Its easy, and its free.

Most of you guys are not actually answering the question the guy asked, you are all telling him how to access mp3's etc stored in a different location on a network.

He would like two or more computers to play the same music at the same time, a problem I am also trying to find a solution to.

I'm also looking for this solution, to synchronize music on two machines or more. Most people are answering with sharing files, which is totally different.

For example. You have party and want to stream music to all the rooms that have a computer, but you want the music to be synchronized and controlled from one machine in case you want to change your playlist on the fly.

I think the software solution would be to live stream, possibly with Shoutcast, but getting it synchronized would be tricky. The hardware solution might be something like the apple i-tunes thing (not sure what it is called).

If anyone know of other solutions please provide some help.
