ipod touch buying for brother, sending to him issues ??

Hi guys, I want to hook my brother up with portable music player. If I buy ipod touch for him, and load music on it, then send it to him to use on his end, what issues will we have ? I would have to register in my name, load up the player from my computer. So when I send to him he could play it and charge battery without issues I believe, but if he hooks up to computer to try and load more music, then he would have problems I think. Should I register in his name with his apple id, but then would I have issues loading his player up for him ? Appreciate any advice, thanks, frank
