I've already started discussion about this on the mailing list: https://lists.berlios.de/pipermail/mapnik-users/2010-August/003498.html

To summarize:
mapnik should allow to set opacity level for final rendered map image on the map object, possibly even on the layer object.

Also this could be part of future map/layer [wiki:Ideas/Compositing compositing].
