What could a library do with a gigabit Internet connection?

Marijke Visser from the ALA Office for Information Technology Policy writes with this provocative question:

What could a library do with a gigabit broadband
connection? What kinds of services could they do that they can't
without that big of a connection? Thinking way away from the typical
services libraries offer now, what are some really big ideas that
would need that much connectivity? These services could happen outside
the library walls, in relationship to other community organizations
and/or government agencies… How would a library hooked up to a gig
benefit its community?
