Thanks for all the feedback and testing!

There might be still an issue with buffer space in current, but we explicitly
bumped the limits for syslogd and kernel sockets. I am not sure what went
on here and the ipsec related socket buffers got full.

Yes, I'd like that very much too. I got it to compile as I mentioned, but
did not have time to work on it more. Perhaps we should just move it to
a github repository or something and work on it together.
