Blogger API and such: extract user comments?

This thread reminded me of a thing I'd once started and then forgot to follow up; I wanted to extract a list of all entries/comments posted by one particular user to all blogs on antville.org. Here is the thread that started it.

With the help of Mr. ubique, I wrote a perl script that worked, with some limitations, but now doesn't work at all anymore. I remember there was another thread on help.antville.org (or was it over at project.antville.org?), but I can't find it anymore. Tobi had taken part in this little exchange, that's all I remember now ...

The script used the "getUsersBlogs" method of Net::Blogger. Were there any changes in antville's handling of Blogger API methods that might have disabled it? Any chances this will work again? Any general documentation of antville's support of the API, or others like it? Any news about this project, for instance?

thx
