Tiffany, did you ever find a 1.9-like workflow? We were about to try Webdav ourselves. It looks like that will not work. sigh. I am so surprised at how hard it is to create a single mini-site (non-SCORM Captivate) so we just have one place to update and one set of files for multiple course files.
I have tried Files Repository but when I point to the Multiscreen file that starts the Captivate lesson as an alias it tells me it cannot find the file. Only if I make a copy, unzip, and tell it to make the multiscreen file the main file can I get it to run. That would be oaky if I could update the zip file for any updated version of the Captivate lesson. When I try that, I get invalid JSON string error on unzipping the newly uploaded zip file. I even tried using the url of the successful copy version and doing a url resource instead of a file. I can make that work, but then I would have to have that working file someplace where all students were enrolled so they could play it in addition to the one of many courses they are officially enrolled in.
Am I totally misunderstanding something about how to get a one stop to update mini site to work across multiple course copies?
