I just returned from the first meeting of the new 20/20 Commission, whose charge, as you may know, is to study how advances in information technology and global trade may require changes in how US lawyers are regulated (and not only in their ethics rules); and if so, what changes.
Rather daunting.
Anyway, the Commission has a listserv in the interest of transparency. The Commission's website, from which you can join the listserv, is at www.abanet.org/ethics2020.
The work is expected to take three years. I'm sure there will much of interest on the listserv. There will also be hearings and roundtables and other ways to elicit the view of the bar, the courts, and others.
