What I would really like is something like Weblate (http://weblate.org), that you can hook in directly to your code repo. Is there anything like that out there?
The perl script written by the user in the article is about 100 lines of code. Doesn't seem like a lot of glue...
Another nice thing that Transifex provides which is not described in the blog is the Transifex client[1]. I wonder why he didn't use it.

As you mentioned, the Perl script was 100 lines and was easier at that moment in time to integrate than to review the python.
Of course once the python client has been reviewed perhaps it would be a more general solution.
