I'm not sure I'd put making the tree-huggers happy in the "pros" list, just out of orneriness, you understand.
I don't know that DRM would be in as much of an issue as you might think. Consider, there's no DRM on the Times' current site, a lot of their raison d'être is to get themselves quoted, and finally, why bother aggressively protecting something that's only perceived as being 'good' for a single day in the first place?
Just my thoughts.
