I am working on lightning talk about JBoss Snowdrop. I will be presenting this on the upcomming CZJUG: http://java.cz/article/czjug-leden-lightning-talks
You are welcome to send me questions. Just send me an email (see my Linkedin profile) or put it into this blog post comment and I will try to address them in the presentation.
I plan to prepare slides in english but the talk will be probably in czech language.
