    I haven't looked into every detail but overall it's a nice piece of work. :-)

    In the README you are talking Netflow 5 and AS path's. I don't undestand why
    you want to pass the AS path into the rtentry structure? Wouldn't the right-
    most AS sufficise?

    A couple of people from OpenBSD and us are thinking of updating and extending
    the routing code and rtsocket framework for things like this most importantly
    the interaction between different routing daemons (EGP & IGP). However this is
    a more long-term thing and more targeted at FreeBSD 6.0.
