The most serious problem with PACER (which is the online docket system for federal courts) is that each 'page' costs the user $0.10, which precludes any meaningful search or analysis of data. I fear that if the government were to provide access to research articles and the like, they may institute similar measures to profit from the availability of this information. I realize that this is an unsubstantiated fear, but it's extremely important to consider how to implement such policies.
Remember, these publishers' very existence depends on profiting from access to journal articles. As such, they will literally fight to the death over this issue.
