Well considering there were like 10 DC++ servers running.... They should really try and ban that next year. Make an example of someone and send them packing if they host a DC++ server.
No! Considering the shocker that was the VC site (shockingly old patches, not all games listed etc...), DC++ was great to not only get the stuff to play but also setting up matches through the chat (odd there was chat 2 years back on the VC site).
What they should do is a real network setup for a lan this size, and actually do some traffic priority or an alternative network for sharing.
