Answer on the last question first: yes, I'm Russian. To be more precise, I'm a Jew from Russia :)

About the first question: I'll see, if I have samples. Actually, I tried it, but then my project was drifted to another programer, so I didn't spend too much time on it. My first quick tests were just fine. AFAIK, the class itself contains some samples, which you can use. Or if you have specific questions or problems, you can contact the author Nigel Coates. I contacted him, when I had some problems.

Anyway, I'll see, what can I do for you.
