I was at a SAE OBDII toptec and found this out about avialability of ALDL
data information:

The final rule for avialability of emission service related information 
is contained in the Federal Register Vol. 60, No. 153, Wednesday, 
Aug., 9 1995.  Page 40474.

This rule requires manufacturers to make avialable all serivce information
supplied to dealers at a reasonable cost.

There is an online computer system called FedWorld which can be accessed 
up to 3 hours a day at 703-321-3339.  This tells what is available, where
and the cost.  It can be also accessed by telneting to fedworld.gov.

The Equipment and Tool Institute, 1806 Johns Drive, Glenview, IL 60025-1657
708-729-8550, 708-729-3670 (fax) provides a annual forum called the Domestic 
Tech Week where (scan)tool makers meet with the big three to discuss new
model changes including Class II data stream information.
