Estimates on a low end configuration of dual 600 MHz, 1 GB RAM is about 500 users for the eLearning scenario. Audio, and real-time session scales linearly for each such machine we add. The current database can support about a 5000 user database before peaking out. This was on a 512 MB RAM system; however, at this point, the database takes about 10 minutes to load initially. So this is the biggest bottleneck.
