(keitai-l) DRM for picture messaging

Has anybody got any information about how the Japanese content providers,
opcos and handset manufacturers tackle the thorny issue of Digital Rights
Management in the area of picture messaging? I assume it is possible for
consumers to purchase images such as comic strips, wallpapers and  cutesy
animations (Hello Kitty).  Is there a mechanism to prevent the
redistribution of these images to other handsets?

Thanks for any help.

Regards

John
