Could Glass-Steagall make a comeback?

Via Ed Cone, some people attribute the current crisis in the financial markets, and the emergence of financial engineering leading instruments that no one understands, to the deregulation of Gramm-Leach-Bliley Act in 1999.

I don't see that interstate banking, for example, has provided much benefit for me, though those barriers came down long before 1999.

UPDATE: Instapundit talks about this, and posts some interesting comments.
