Not too surprising, unfortunately. Try the iLiad, though. I think you'll like it. And the software environment is relatively open, so if you need to create some custom sw it can be done. I think iRex is also still very interested in B2B models if you want them to customize the environment somewhat. (The rest of us would be very happy if you can get them to allow more items to be displayed in the ContentLister at once.)
Good luck with this project, and keep us posted!
