good luck with the project

with namecoin - you don't need to use browser plugins so you should probably edit that part out..
all you need is a DNS that supports namecoin..  you can run NMControl or other tools to do it all locally for complete trustlessness (it's a word?).. if you trust an external namecoin dns server, like Khal's, you can do a simple setup by using a browser plugin (this is maybe what you are talking about?)
