As we roll out a new network, on one of our links it is remarkably cheaper
to run a T1 ptp vs. MPLS (running 66% data, 33% voice).  Based on comments
received from this list (much thanks,  you know who you are) MPLS
satisfaction seems to be determined by backbone noc competence, not the
technology itself.  So back to price....if I consider layer1 issues to be
equal in either scenario, and aggregation/meshing/hardware is not a real
concern, it seems to me that a correctly configured, directly connected pipe
would work as well as mpls, with the benefit of local control of my routers
and owning any incompetence.

Also, the PTP T1 has fewer hops (probably lower latency), fewer points of failure, fewer ways to break, less complexity, etc. I can't think of any reason you'd want to go with an MPLS(VPN) solution over PTP solution if startup and MRC were equal.
