Eoin,
Our easy-tags ({JFBCLike}, {SCGooglePlusOne}, etc) do make it very easy to add the tags to any extension. We're always considering new extensions to support natively, but as you've noted, we currently don't support EasyBlog or Zoo. We're planning a new plugin system that will make adding support for other extensions easier in the future, but it won't be ready for some time.
Unfortunately, I don't know EasyBlog or Zoo well enough to guide you through their template systems. If you know what file you'd need to edit in their components, we can gladly help you with the tags you'd need to add. However, we simply don't know every extension or each's structure in a way that we could provide a guide for all of them.
Hope that makes sense. Wherever we can help with the JFBConnect functionality, we gladly will, so just let us know!
Thanks,
Alex
