The NIH is already actually doing that, at least sort of- any article reporting NIH-funded has to be submitted to PubMed Central, from where anybody can view and download the full text, figures, etc. I believe that there's an embargo exemption that allows journals to hold off on submitting to PMC for a few months or maybe up to a year, but after that it's public.

Right now, it's just NIH, but it's only a matter of time before AHRQ and the other biomedical funding agencies get in on the action, and there's no reason (in principle, anyway) why NSF or DOE couldn't also join in or do something similar on their own.
