I just recently made the suggestion to have PunBB as one of the selections to be used on Cpanel Theme's Fantastico product. For those unfamiliar with this, it's a CPanel/PHP based Web application. It integrates with CPanel and gives hosted web clients the ability to automagically install Open Source Applications.
I use Fantastico on my hosting service, it makes installation of products a breeze and potentialy could bring big numbers to the community since its one of the most popular addons for web hosting services.
So I hope you don't mind Rickard... it is getting some support to be installed next to the three other popular but bloated competitors on the application already.
