Visiting Professor Jonathan Zittrain is quoted on the possibilities of a free online feed of all U.S laws and regulations:

Congressional legislation this year to enable a no-charge
online ‘bulk feed’ of U.S. law and regulations down to the local level is the
aim of a campaign supported by Google, the Center for American Progress,
O’Reilly Media and law-school centers and professors coast-to-coast associated
with what’s called the copyleft, the organizer said. No enactment is assured in
2010, acknowledged public-records activist Carl Malamud, the prime mover behind
the campaign for the proposed Law.gov. But the push, including months of
workshops and reports, will advance the cause of opening up to public use the
rules made by public officials and the work leading up to them, he said Tuesday
at Stanford Law School.

Jonathan Zittrain, a Harvard law professor, said he’s excited about the
‘prospects of a generative platform’ that would enable all kinds of uses of the
information — including the addition of annotations, commentary and discussions
of relationships with other information — some unpredictable. Malamud said he
and allies are ‘looking at a variety of crowd-sourcing’ strategies for adding
information.
