Netfilter Developer Workshop 2008 in Paris

I'm currently at the netfilter workshop 2008 in Paris, France.

It's always sort-of a mixed experience for me. Obviously it's great to spend some time with all the great hackers who work on various aspects of netfilter/iptables (and now finally also its successor that is so-far called nftables). On the other hand, it's been about three years since I last actively contributed code to netfilter, which makes me sad. I'm still excited about it and have many ideas that I'd love to implement. But where to find the time for it?
