:I've done that running mpd to split the load over the tunnels from the 
:if either tunnel goes down mpd hickups nd hten everything keeps going..
:mpd does this for me..

    That looks almost perfect for the colo idea.  I see how the links are
    set up and I see the bundle directive, but how do I configure a common
    subnet?  Do I specify the same subnet for all the links and make them
    part of the same bundle (on both ends)?

    Is there a way to backhaul the bundle onto a single TUN interface?
    Or is that what ng_eiface is for?  I need a tie-in for PF's QOS.
    There's no choice about that, my network is 100% saturated 24x7 and
    if I don't use PF's QOS with fair-share scheduling it becomes unusable.

    Looks like I might have to update netgraph on DFly to use mpd, but it
    doesn't look too difficult.  But, gods, all those M_NOWAIT kernel
    mallocs...  how can that possibly be reliable?
