[c-nsp] RSPAN over WAN/MAN

I have an application where I need to copy traffic at a remote site and
record it at a central site. At the remote site, all devices are in
their own VLAN and are all connected to a single WS-C2960X-48FPD-L
switch. At the central site, there are several switches I can use for
the recording server (until the server is set up, using a laptop and
Wireshark to test).
At first, I thought RSPAN. I've never done an RSPAN session, but I got
it working in a test setup at the central site. I tried the same thing
with the remote site, but can't get anything but broadcasts. 
The central site and all remote sites are connected to each other over
AT&T's Opt-E-MAN switched Ethernet service. Will RSPAN work over
Opt-E-MAN? I'm starting to think maybe not. Should I try RSPAN over a
GRE tunnel? Can I use VACL capture? I haven't tried to set up either
