Comment (by hinder):

 Speaking for PunctureTracker users at the AEI, we do not use anything
 beyond the current interface between PT and CT.  I suspect the only people
 who might use anything more would be Christian and Denis.  It would be
 very nice to have a mechanism which triggered certain events when two
 spherical surfaces got close to each other.  The immediate application for
 me would be to reduce the number of refinement levels as I think is
 possible with PT, and to set a flag which triggered run termination a
 certain coordinate time later.  The former could be handled by
 CarpetTracker, but the latter would be handled by something else.
