Hi Lucas, thanks.
The plugin we use is not available yet (AFAIK). It was one our developers came up with as an alternative to FeedWordPress. As they felt FWP would take too long to code review and might not be performant on a multisite setup. The Syndication plugin is a simplified version of one auttomatic have in development. It is not AFAIK released. At the moment it is not as fully featured as FWP. I’ve some info for Glow Blogs users on the help. I am a lot more familiar with FWP using it on ScotEduBlogs.org and edutalk.cc for a while now.
