I don't know how many others use AltBinz in the same way I do, but essentially it's unattended for me. It checks the RSS for NZBs, gets them, decodes them, places them on the network and cleans up after itself. I only hit the UI to see if I can see why something might not have come through. The only problem I have is that I have to leave a user logged in to achieve this - The server has it runing on console which ideally wouldn't have anyone logged in most of the time.
And to my polite request, can it be written as a service rather than a user app? UI features could be kept as a user app, but the automated features moved into a service.
I know I'm not supposed to comment on how easy this would be, but... Well, clearly it wouldn't be. But I think it'd be worthwhile!
