We did a survey around 2008-9 in Sweden and concluded that the risk
of large hysteresis IPDV and Q-in-Q outweighed the attractiveness
(mainly price) of running on top of somebody elses MPLS. A major
contributing factor was, and is, also that we ourselves are running
MPLS for our logical separation needs, and that we predicted and got a
lot of real-time critical RTP streams on the internal WAN. We bought
"Gigabit Ethernet compatible channels" over mainly dark fiber or WDM
and included text in the call for tender about not even trying to offer
MPLS-based L2.. This was done under EU Public call for tender legislation,
which was a challenge. We are quite happy, and slashed our old inflated
price for relatively small SDH links by a lot.

If, OTOH, you are not a very distributed radio company trying to do
RTP in 48kHz 24-bit linear stereo over internal WAN, using multicast,
you might be fine with a MPLS offering...
