2 Music Libraries on 2 different computers

[BrickAlley]

I have a laptop connected to an external HDD that has a large amount of music on it. I've gotten it to stream to my EVO with no problems. Now I would like to also stream a large library from a desktop pc in another room. Will I need to create a network between the 2 computers or can I setup it up another way. I've been poking around trying to find the answer, but I've not had any luck, so I'm turning to you guys.

It would be fine with me if I could avoid networking the 2 computers, but I'll accept whatever options I have. LOL
