Maybe make some piece of code that automaticly connects to darkcoin.io. Then forking problems should be lot less as everyone is kind of forced to connect to the right wallet.
The problem with that, as I see it, is that it would break one of the fundamental paradigms of Darkcoin and Cryptocurrencies in general. That is that they are decentralised. If you make a connection to darkcoin.io a necessity, then you introduce a single point of failure. If the Fed's wanted to come after Darkcoin, then all they would need to do is come after darkcoin.io and shut it down.
