I have two issues with that.
One is that it's not just a question of ever being able to understand -
it's also a question of being able to present the required information
in an understandable fashion and get a valid configuration back in a
reasonable manner during installation. I could abort configuration and
let people come back to it later or require people to do stuff
themselves but that's kind of defeating the point of trying to help
people out with the configuration.
The other is that for most of these users Leafnode is functioning as a
proxy providing offline cache services. It's got one upstream, one
downstream and its only role in life is to add offline support to the
client. It might be possible to have it act more like a full server but
that's not the point. That's the kind of person for whom I'm trying to

That's not an entirely useful solution for Debian - I can't rely on
systems being network-connected at the point of configuration. I could
play games with trying to generate something while connected.
Attempting to validate the hostname too strongly is a loosing game - if
you want to avoid things like big ISP domains you'll end up with a
mighty long blacklist.
