I guess I see it as the same Bitcoin-Qt project mainly by @laanwj (ie, same maintainer = same project), and @gavinandresen the project lead of bitcoin_d_ (which happens to share the same git repository). I don’t really care what you choose to name the client, but some distinction between Bitcoin and this Bitcoin client is needed.
