Well, I just read what you wrote and I know that the dotlrn package is dominating most of the openacs development. That's good for me since e-learning is my field of interest.
I've also had to weather much of the LAMP criticism I hosted the http://lampsig.org in my office for over 2 years and finally kinda gave up because it was turning out to be a widget fest where most of the people didn't have a interest in enterprise level development.
I will remember what you have suggested and check it out in the various circles that I run in. I'm very curious to know what's doing with naviserver since I worked with them before AOL purchased the browser and as far as I can tell, did nothing with the publishing parts which were quite useful to me. I would like to see oacs do a good job of pre-press since the market is wide open with quark, InDesign and Scribus being the consumer apps that most people use.
I did see where the was some talk about using the TEX engine, which would work very well for me since I have a good friend who is a tex expert but It seems to have died some few years ago.
