The feeling I get from reading the discussion about the binding, is that it’s a work in progress. (But the progress is maybe a bit stalled; I assume life gets in the way :)). But the binding did/does function for the large part, and maybe for others without that HTTP error, since the binding author didn’t seem to recognize it when I mentioned the last time I had contact with him.
This makes sense, of course. The snowball keeps on rolling now.
