Thanks all for the support. Another quick update with another code example for the new library:
I’ve now managed to get the DNS services working with public names, the example below is code using the new library to create a new public name “shanetesting” and a service within that “www” which when combined would be accessible through safe://www.shanetesting in the safe browser.
Obviously, you would never actually write the code above (since it deals with multiple concerns in the same function) - it was just a simple way to show how it could be used in as little code as possible 
This is a great milestone and means I’ve got about 33% of the functionality I need to build complete. Thanks to all of you for the kind words and support so far.
