We've asked all customers, and nearly all of those have had us go ahead
and filter it inbound into their tailcircuits.  Some we're also filtering
outbound, again at the tailcircuit.  A few have asked for exceptions for
some home or branch offices, but that hasn't gotten unmanageable yet.
Most of the ones with complicated remote-access needs use GRE.
