Streaming Video from One Laptop to Another

[skyline889]

This is probably a noob question but I have my main laptop hooked up to a 1.5TB external hard drive with all my media on it. Is there a way to stream this content over WIFI to my second laptop? I live in a dorm so I don't have access to the router which is why I was wondering if I could just link the two via their WIFI adapters and if I could, how I would do it.
