With news of an official Direct Connect port, ronnlund let us know that there is a DC++ port in the works:
- Hi, a few weeks before the news of the Direct Connect for OSX was released I managed to get a coder to port Direct Connect Plus Plus (sourceforge project) to OSX, the client is allmost done. DC plus plus supports mutliple Hub connections and have loads more features than the original and it's open source.
Further discussion is in this Swedish thread.
