    Which is where the problem is, it should be.

    Because what you want might not be what others want. Suppose you're fine
    with your torrent client/irc client/etc.. to loose their network
    connection when you're not behind your desktop so you don't add suspend
    blockers there.

    Me, I'd be ready to administer physical violence if either of those lost
    their connections when I wasn't around to keep the screen-saver from
    kicking in.

    This leads to having to sprinkle magic dust (and lots of config options)
    all over userspace. Something that gets esp interesting with only a
    boolean interface.

    In the example above, having an active net connection would prevent my
    desktop from suspending, but what if another platform can maintain net
    connections while suspended? Do we then end up with arch specific code
    in the net-stack? I'm sure DaveM would love that.
