PPP gives you authentication (PAP/CHAP), plus standards-based
inter-operability
HDLC is quasi-standards-based, having been developmeped from SLDC
originally, although different manufacturers are inter-operable to a greater
or lesser extent (Nokia for instance support "Cisco"-HDLC on their firewall
boxes). HDLC has a slightly lower overhead than PPP.
I tend to use HDLC on internal leased-lines where I *shouldn't* need
authentication, and PPP on dial-based stuff.
