Sorry for the delay. I just flew in from Madrid. We had a great conference there. People from all over... and a lot of great ideas.
One of the great things about this project is that there is quite a number of companies offering support around openacs/dotlrn. Out of the 60 people in the conference 1/4 were consultants, 1/4 managers, 1/4 teaching staff, 1/4 researchers (of course most would fit in more than one box). I think no other open source around elearning has as many companies, check out:

I think LAMS support will be provided by their creators. Ernie should be able to provide you with more information.
cheers
