This is pretty much an open question at this time, and as Agile evolves I think we can expect to see greater use of it outside software development settings.

See this discussion for a good blow-by-blow: http://stackoverflow.com/questions/1702128/can-i-use-agile-in-a-non-development-project 

BTW, I'm going to be pedantic: scrum is an Agile tool. Also, Agile was designed for software projects - there's no shift in focus as you suggest.
