River, WebCT has merged with a company named blackboard. I don't think their pricing is going to be different based on who they think the classes will be targeted towards, but for the record I only communicated an interest in evaluating online instructional delivery tools.
I made no mention of any organization, only the approximate # of annual users.
Maybe webCT was low cost but after the merger they are upgrading their target market.
I haven't personally evaluated the software to determine if it is worth a hefty price tag...but I do think there are likely other open platforms that can suffice.
From what i've seen in the demos, it seems more like a way to deliver e-learning and canned content than live instruction.
