Actually, as odd as this is going to sound, under property law, your wife and kids DO have explicit use of the content. Also, taking it a step further, your wife and yourself would, presumably, be in a common law situation (having been married and licensed by the state), thereby allowing her complete access to this media.
I don't want to sit here debating property and IP law all day, but unlike the last poster, this IS clear cut, it is NOT 'muddy' water, and sharing this music with friends IS illegal. It's been adjudicated out to the nth degree. One only needs to read about the judgements currently being handed out in BOTH the RIAA favor and against them to understand the situation. Arstechnica.com does an excellent job of reporting and summarizing them for the lay person, for anyone who is interested.
Let's assume this is illegal, for argument's sake. Let's also assume you authorize a friend to use your library. That computer, it's IP address, and all pertinent information is on Apple's servers; after all, you just authorized that computer directly with Apple. If the RIAA jumps in and decides to read the forum thread and sue both the distributor of the content (the OP) and his friend (the recipient), they will not only sue the OP for illegal file sharing, but sue him for distributing the content, which, in the court's view, makes him more culpable in this situation and thus responsible for stiffer penalties than his friend.
In the Jammie Thomas v. RIAA in Minnesota, they went after her for distributing the songs and found her liable for higher damages as she was actively distributing copyrighted content to others. Now, before anyone chimes in that the case was declared a mistrial, it wasn't that she was found not guilty of sharing copyrighted IP, it was the fact that her attorney managed to convince the court of appeals that they hadn't proved that any actual sharing had taken place, only that she had offered them up.
What I'm getting to (yes, there is a point here) is that with the iTunes method of sharing, they will not only know you shared, but EXACTLY who you shared with. Just my $.02.
