The hubzilla_wp WordPress addon posts from WP to Hubzilla, but there are two requirements:
- It requires the Twitter API addon be installed in Hubzilla.
- To make comments flow back and forth you'll also need to have the wppost addon installed on Hubzilla. This addon handles the Hubzilla to WordPress direction but also contains some code which can communicate with plugins on the WP side to share comments.
As far as Pterotype, I started working on this several months ago and the project was so new and changing so quickly that I decided to wait until it settled down a bit. It probably is stable enough at this point to sort out the remaining issues. FYI, I no longer work on non-nomadic protocols (no exceptions), so it you want it, roll up your sleeves and dive in.
