Well by hosting i mean:
I have a domain. But the domain needs a page to be displayed. And the needed files like index.htm and so on need to be somewhere. I would update the dns string for the adress so it gets directed to the files. Or am i completely wrong? I don't
Want to redirect it to a normal .com adress or so.
Ah sorry, then I misunderstood you. I acknowledge that if you also need webspace and don't already have a server somewhere (which you can rent also anonymously with Bitcoin, if you like, which will probably be more expensive but also give you more features if you can make use of them) then you can't do "namecoin alone" and indeed khal's service provides for you. What you can do yourself is let your .bit domain redirect you to the IP of your server.
