I have seen the website, whitepapers, and different videos.. from promos to some guy giving a talk.
But the only access you get to actually use it is a waiting list, unless you consider some of the underlying IPFS technology it uses that you can get from other sources (which is a different beast entirely).
It's likely I'm not meeting some prequalification requirement for the access, but this unfortunately means I can't get excited. If I can't test it anywhere and have never made it run myself, I have to withhold judgement.
