Embedding it within a site isn't as useful for me, personally. Possibly for others. Perhaps the ability to pay for a permanent URL (or chat room ID) so a team can bookmark it for times when they need to chat. Or a URL I can easily send to someone without having to always "register" a new one. I can see that being part of a paid tier (along with TLD mapping, UI customization, etc).
