Can we have South End-style infrastructure to support South End-style density?

At last night's Task Force meeting, Harvard's consultant suggested that Rollins Square is a valid precedent to consider when thinking about the scale of what Harvard might build in Barry's Corner. In many ways, Rollins Square is a great project as I mentioned in a 2008 post:

Rollins Sq won the John M. Clancy Award for socially responsible housing in 2006. The jury noted that the six-story buildings and four-story townhomes "fit well within its mid-rise neighborhood". It also received a Maxwell Award from the Fannie Mae Foundation for outstanding development of affordable housing and an award from the Boston Preservation Alliance. 

 But buildings like this need to be considered in their context, and the context of Boston's South End is very different than North Allston, particularly in terms of its transportation infrastructure.

Using the MBTA map at http://erikdemaine.org/maps/mbta/, here are the subway lines within approximately 1 mile of Rollins Sq and Barry's Corner. Which location is better able to handle large numbers of residents, workers, and visitors?

If Harvard was willing to talk about a commuter rail stop, a revived section of the proposed but since mothballed Urban Ring, encouraging Harvard employees to live in Allston and walk or bike to work, or other ways to mitigate/reduce the transportation impacts of Rollins Square style housing in Barry's Corner, I expect that their plans would be received much more favorably than they were last night.
