code177, read the "at this moment" in your quote. At this moment Ovi for Maemo is not public, nobody can publish (as in make public) any software for the N900 simply because there are no Ovi pages for the N900. Simple as that.

One day Ovi for Maemo will be public, the terms and condition will be public and you will see that being a Premium publisher is not a requirement in order to publish apps for Maemo in Ovi.

None of this has anything to do with open source. The previous step (having a Tax ID or VAT) still applies. The Premium brings the hurdle of the liability insurance, which is what I'm saying that won't be required to publish apps for Maemo.

Just wait till the announcement of Ovi for Maemo. Keep sending your questions to the wiki page. as you see we are doing some homework in order to answer them.
