It would be easy to do as a GEOM class, but for real-life usage it would have to be directly in GEOM. Actually, I've done the logging part twice before, but it's not convenient to stop the geoms to insert a logging class in front of them. PJD has talked for some time about making a sort-of "hot-pluggable" mechanism in GEOM in which classes could be inserted in between two other classes without stopping them, but this will take time... There's another consideration: Apple can do it because OSX is shipped "as-is" and doesn't change much when you install it, but FreeBSD is always customized after installing. This doesn't prevent the mechanism to be implemented, but it would require it to be very easy to use.
