Does anyone know of a good site to host/share powerpoint and keynote presentations privately? I have a requirement that users should be able to view presentations and download slides individually as well as download the whole presentation. The user should also be able to tag presentations and individual slides within the presentation.
I've checked out slideshare - this is the only site I can find that handles keynote presentations, but I don't thing you can download individual slides. There are a bunch of other sites that seem to only handle powerpoint and not Keynote.
Does such a thing exist? If not, what are my next best options?
