anyone using TopClass systems? and sharing ULMs?

[James Salsman]

I'd like to hear from anyone who has been using the TopClass 
web-based instructional courseware product from WBT Systems, 
and in particular, what kind of a "library" of TopClass units of 
learning material (ULMs) are made available at your institution?  
Of particular interest to me is whether ULMs are shared between 
institutions, and how that is handled; e.g., are they shared by 
means of commercial transactions or is the process more like 
interlibrary loan? 

TopClass is described at http://www.wbtsystems.com/intro/index.html
-- that name seems to be resolving poorly at some sites; if it 
doesn't work, try:  http://208.204.2.10/intro/index.html

They also sent me this document describing their 2.0 product
release, due out in February, which looks really excellent: 
 ftp://ftp.bovik.org/topclass-2.txt

I also put the Instructors' and Administrators' Guides which are 
distributed with the free, four-user version of TopClass in my 
anonymous FTP directory -- ftp.bovik.org/topclass_*.pdf
