FYI, as the original Workflow is not working anymore, I've published a new working Workflow: Amazon Affiliate Link Generator.
You can find it here: https://www.packal.org/workflow/amazon-affiliate-link-generator
I've created a new Workflow that allows you to search files on KickAssTorrents (KAT mirror configurable), select a desired file from Alfred context menu and automatically send the download action to a Transmission server.
You can find the Workflow (based on a mix of scripts and workflows available) on Packal:
http://www.packal.org/workflow/kat-search-transmission
All you have to do is to configure it by settings the requested variables related to your Transmission server.
