ok, I can confirm you're right.
Anyway I believe we should just provide sensible defaults to work out-of-the-
box for a basic setup - and our basic setup for ssh is dropbear. If a user 
wants to replace it, he has his reasons and I assume he is experierenced 
enough to know what he does and how to do it. We have to draw a line somwhere 
otherwise we are always behind trying to catch up with config requests.
Instead I prefer a small chapter in the wiki.

Already added to two lines to /etc/sysctl.

Depends what you define as "real". Currently it's just a tunnel with aiccu, but 
I expect changes in 2011 as my ISP plans to deploy ipv6.
