I think a project like Ethereum, which should be in full swing by the 4th quarter of this year will solve this issue. The Ehtereum network can secure against the 51% attack, and alt-coins can be implemented on top of it for just this purpose, and the ease of implementation, since Ethereum comes with a full scripting language. Ethereum isn't an alt-coin - it is a system to create 'smart contracts'. One such smart contract could be the implementation of a coin like AuroraCoin. Any alt-coin you can think of should be able to be implemented on the Ethereum network - and the chances are they will even be more feature rich because of the EtherScript language.
