Overview
In the system depicted above an Open Source Commercial Off-the-Shelf (OS COTS) chat application generates a log of each session. This is behaviour common to most such systems. It could be inside or outside Moodle, it doesn't matter. At the end of a session a Log Analysis Program (that's the bit I am creating) examines the log, separates each student, analyses their contribution to the session, and appends the results to individual student reports.
In a bit more detail
A sample of chat might go like this:
Tutor [09:00]: Good morning class! Today I want to discuss the news that the government is considering raising GST from 12.5% to 15%. What difference is this going to make to a typical brasserie?
Biggles [09:03]: The prices will have to go up. It may discourage the public who are already hard up.
Tutor [09:04]: Good, Biggles. Who else has some comment?
Tiny [09:05]: ugh thatz stupd, ppl nd 2 eat
System [09:05]: Tiny! Texting language is not permitted in this chatroom. Two lives left.
Tutor [09:06]; OK, Tiny you make your point. But please make more effort to be respectful, and to form complete sentences in plain English.
Rodney [09:06]: Chefs who can be creative with low-cost ingredients will be the winners.
Tutor [09:07]: Very good, Rodney. You are really getting the hang of this now.
The students can use nicknames because the system knows their real names. Note that the tutor is encoding her replies: when she says make more effort to be respectful the system will recognise that response against Tiny's name. Equally, so will it recognise Very good, Rodney and the text analysis will score his complex word in.gre.di.ents also his perfectly formed sentence. The system uses regular expressions to search the text for certain patterns. The system can also count the use of subject-specific words supplied by the tutor.
Institutions don't have to tie up their senior tutors on this type of work. Part-time and otherwise under-utilised teaching staff can be enlisted, and the requirements for literacy and numeracy education can be codified into the system.
This is a prototype I'm building. I don't pretend there won't be obstacles along the way. I value any feedback anybody wants to give me [lmsfarm@gmail.com].

LMS Farm expands to Learning Management System Farm, because that's how I started... installing and managing multiple instances of Moodle for industry trainers. These days most people can sort out Moodle for themselves, and I am focusing more on interactive tools for learning.
This project has grown out of ideas of collective intelligence and connectivist learning. It represents something of a quest for a Learning Facilitation System, in contrast to a Learning Management System. Possibly it first sparked when 
This Flash eToy was started by Sherryl Hatton when she was in the Integrated Learning Services (ILS) department at Aoraki Polytechnic. When Sherryl left, I picked it up. It is now going into its third iteration. Student chefs can drag and drop kitchen fixtures and fittings, and then mark out the work flows. The student can save their effort for tutor feedback, or as an assignment. Aoraki's award-winning chef 
This is an on-going thing, working on these Lightweight Methods. Some learning theories and learning methodologies are so complex it becomes hard to apply them to real world projects in the time available. Unless institutions are very rich and are willing to sponsor educational experiments it ain't going to happen. So we have these bits of bamboo scaffolding, and we work into them. And guess what? They just work. The students learn e v e r y time! Just now it's founded on 
Student-user profiling in connectivist learning environments was my dissertation project. Some useful tools came out of the project. As I get time I plan to make each of these tools available for people to try, play with, or even use! The first of these is the
