        I'd much appreciate IPv6 support, and there will be virtually no
        need for NAT for me then.

        (There's an obvious interest in P2P in the free software
        community, and effective use of P2P at the world scale is only
        possible with IPv6.)

        I'm not quite sure on what boxes were considered, but
        personally, I've ended up using an Intel Atom 330-based system
        in a Mini-ITX (InWin BM648) case as a router (1 Ethernet
        interface on-board + 1 PCI + 1 USB).

        Of course, it runs Exim, Rsync, Apache, read-only public NFS,
        Tor, some traffic accounting, etc. just as well.

[…]

        But once again I wonder, given the sheer variety of drivers'
        code written for Linux, how NOT to duplicate the effort?

        To my mind, the approaches considered so far were:

        • glue code;

        • Xen with a Linux-based dom0;

        • message passing on top of Linux:

          – with a user-space daemon;

          – with a kernel module.

        Do I understand it correctly that once a Mach could be made to
        run in user-space (the same trick as with User-mode Linux),
        making Hurd run on top of it will be straightforward?

        This effectively makes the Hurd only a single command, namely:

# apt-get install hurd 

        away from from a J. Random (Debian) GNU/Linux user.

        For those wishing for a better experience, a Linux kernel module
        version of Mach could be developed at some time later.

        Then, the sole question will be the tasks that Hurd covers.
        Eventually, some users may find that they use little or no
        native Linux modules, but instead use the Hurd ones.  The
        transition to GNU/Hurd[/Linux] will be over for them.
