	FreeBSD and DragonFly both have two PPP implemenations. A kernel
based one controlled by pppd(8) and a user mode one implemented in ppp(8).
The latter uses the tunnel interface (tun) and does everything in user
space. User ppp does provide channel bonding (I've used it) but is I
believe less sophisticated than mpd.
