Let me give you a "parochial" response since you asked.  I'd use a
modified version of OSPF that can deal with both networks and ptp links,
and has been extended to provide QoS routing abilities, i.e., advertise
available bandwidth and use a path selection algorihm that is sensitive to
bandwidth.

George Apostolopoulos implemented such an extension to OSPF on GateD,
based on the draft we had put together, and we are trying to get this code
released externally.
