    Hi Joe!

    I'd love to know more about this... I've got access to do just that, but
    don't know where exactly to start... We use ADSL which is delivered over ATM
    transport - we have mini FreeBSD boxes on the client site, and a FreeBSD box
    as a router in the colo as gateway - we're setting it up to do mesh VPN
    routing, and packet filtering, etc. but I guess we are in the right position
    to set something like that up for anyone wanting more bandwidth...

    The nature of the ATM transport is that A can see B and C can see B, but A
    can not see C (atm path restrictions - it would have to be routed or bounced
    off B, and although I've heard people mumble about /32 subnetting, I'm not
    sure how that would work)

    A--ADSL---\
              B --- Internet
    C--ADSL---/

    Thanks.

    m/
