IPv6 back for --- just in time for IPv6 day

IPv6 ready is now again reachable via IPv6 (at 2001:4ca0:2001:42:230:48ff:febb:4bca) --- as it should be for the first P2P network that fully supports IPv6 (we've had partial support since about 2002).

Reviving the discussion: gnunet's p2p chat

It is on the todo list for GNUnet, but nothing about it can be found on this website. The discussion was mainly on GNUnet's old website, long gone, but a leg of the discussion (and "possible design" for GNUnet's P2P chat is here:

Unfortunately the old Drupal had a quite more extensive discussion (at least one thread that started here, and went on with possible implementation details), but, well, better small documentation then none :-)

And just compile it using:
$ tar xvfz libtool-2.4.tar.gz
$ cd libtool
$ ./configure
$ sudo make install

$ libtoolize --copy --force
$ aclocal
$ autoconf

systemd design issues

First, I should say that I'm a big fan of the overall approach taken by systemd for system starting and replacing alternative init systems. In particular the idea of having systemd pre-bind to addresses and then pass the bound socket to supervised processes is exactly right. However, I think the specific implementation choices in the current design have some issues and wanted to put them into writing for discussion.
