Interestingly, at the end of the discussion Assange makes an early reference the concept of bitcoin-based 'subcurrencies'.
Some believe this will become the predominant model for future crypto-currency innovation. Much as Google, Ebay and Paypal quickly filled their respective niches in a new landscape, bitcoin is rapidly becoming entrenched as a defacto standard. The eventual fate of the current 'alt coins' is less than certain. Instead, future subcurrencies may appear to fill specific needs, fully or partially backed by bitcoins, much as the US dollar was once backed by gold.
That... sounds ridiculously awesome.
