Hi David,
Congratulations to E-lane people initiative in providing a user tracking package for openacs/dotlrn.
I'm working with oacs-5-1 branch with dotlrn - thanks Tracy to tag it with alpha ! - because of LORS and made some presentations here in Brazil for people interested in LMS systems. They really agree SCORM is a great feature in dotlrn - I made some presentation with reload scorm editor - but all of them claims about lacking of user tracking system.
I read your report and if you and Rocael want count on me to some help - maybe alfa/beta tester, documentation, improvement on tcl or adp front, testing data models on postgresql ...
BTW, do you know who i could contact in UNICAMP/Brazil about E-lane? I saw UNICAMP is a partner of E-lane here in Brazil and i would be informed about what they are doing.
