Lean and the Smaller Companies

I recently read this article, authored by Glyn Finney, over on the Achieving Business Excellence site, about the effectiveness of Lean implementations within smaller organizations. Two interesting points stuck out:

1. Because smaller organization do not have the resources to employ Lean management senseis to drive the initiative, many now have the option of robust online courses.
2. Smaller organizations often comprise employees that work together much closer than their larger counterparts -- the Lean management systems will reveal waste much quicker.

Do you agree with Finney's points in his article? Do you think that online courses are improving to the point that they can be used in lieu of a sensei? Do any readers have any experiences with online courses? How about experiences with Lean initiatives in smaller companies? What were the particular challenges?
