I’ve been posting a lot on the NetworkedMediaTank forums lately since I recently developed an application for the Popcorn Hour (and Optware/other devices) that improves the management of Usenet related functions. The application was originally intended to simply grab all the bookmarks from a users Newzbin account and queue up those NZBs to be downloaded by the users usenet application (NZBget by default).
This means a user no longer needs to go through the manual process of downloading an NZB and uploading it to their Usenet client — which means they would either need to set up an elaborate web-interface setup (such SABnzbd+) or would need remote access to their usenet client in some other fashion. The user can now simply login to Newzbin and bookmark the item. Newzbook takes care of the rest of things and starts the download automatically on its next pass.
The application has now expanded to include a number of other functions such as a mobile friendly Newzbin search and NZBget interface. You can find more details about the application on my googlecode page or on the NMT forums.
I should note that I do not give out Newzbin invitations to anyone I don’t know and I strongly do not condone piracy.
