The answer? “We’re working on it”:
Because of some restrictions in terms of Policy issues i.e. access control (who?) and Digital Rights (licensing, liability), we can not provide this feature at this time within our WMSs. We are addressing these issues as we speak as part of the overall effort through internal means and within the Open Geospatial Consortium GeoDRM group.
We will keep you informed ….
All the best for now

GeoDRM? I should have guessed there’d be such a thing. Soon we’ll be faced with the phenomenon of illegal layersharing:-)
GeoDRM stands a better chance than DRM for music or video, however — music and video have as an achilles heel that they are not interactive, so they can always be recorded at the experiential stage. Dynamically served maps and data appear far more difficult to “record” for playback. Perhaps in the future we will have pirate Earths, where de-DRM’ed data is available, but I imagine the cost of running such a place would be prohibitive.
Interestingly, the library metaphor is bandied about quite a bit in the context of serving spatial information for free. Rights are protected, but access is subsidized as it is perceived as a “community good”. This is where the Atlas of Canada appears headed.
