Questions about Dfinity

Hi,
I’m (obviously) completely new to all of this, I just saw this, it LOOKED damn cool, so I surfed on in and… I have some QUESTIONS! :slight_smile: :

  1. Can one write websites which have backends written in Javascript (ie. node.js) in this thing?

  2. Can any person, including a guy at home become a hoster of this thing? Is it possible to do that on a Dynamic IP?

  3. Can I be a hoster from Calcutta, India? ie. can I get paid in Rupees using this thing (with your “token”, whatever that is?)

  4. Is it possible to harness the GPU on the server side using this thing? ie. for remote game streaming services and suchlike?

Ok, that’s all to start with.
Thanks :slight_smile:
