Howdy Wes,
Thank you for your response.
Bill’s tutorial is not a plugin, but a function and a piece of javascript that can be added to the child theme in order to modify its pagination behavior.
I asked Bill, and he said the solution would be to ask the theme developer as you’re familiar with the structure and elements of the child theme that need to be edited in one of the functions lines (‘be_post_summary()’ replaced by whatever function is used to load the posts excerpts in the category page) to ‘trigger’ the javascript loading the next page.
Hopefully somebody knows, as it seems like a wonderful idea creating a ‘stream’ of loading content as we’ve all become use to facebook/twitter-like feeds of content.
