yeah I just had a look.. it looks good. I wanted to do something similar a while back but then figured that WordPress.org is gonna do it eventually like they did for Premium themes. Anyway, it’s not overly complex to design/create a simpler version of the site in question. It will be a big project though so the main question is.. will it pay off for the time and effort that will be spent developing it?
I do however need a similar system for one of my other projects that I am aiming to do next year so there is a good chance I will end up developing it and then productize it
