I'm pretty sure Amazon would not let you add items to someone else's wishlist. This would mean that anyone could send arbitrary items to anyone else. While I'm sure you have good intentions, other people could use this to send inappropriate items ("Honey, did you order this Foxy Boxing DVD?") or do mail harrassment. You can receive unsolicited gifts using the Wishlist, but at least it's a pre-approved item.

As far as I can tell what you're trying to do, you'll either need to get the person to add the item themself or get their address some other way.

Thanks. Yes, the problem you are highlighting did occur to me after I posted my question. I note though that Amazon has kind of a social network feature where you can add friends and family and set privacy options on that basis. I guess receiving random gifts from people or having them add items to one's wish list would need to be limited to such 'friends'.
