We are hoping to start working on SSO by the end of the month. Please note that we are considering making this part of a Premium service that would include other "pro/enterprise" features. Though our pricing model would be much more friendly than what you normally see for such services.

Thank you for the requests! I think the first part of this Idea is related to http://feedback.ryver.com/topics/42-have-images-open-in-ryver/, and the second part is related to http://feedback.ryver.com/topics/32-search-of-uploaded-files/, so I'm going to consider this one a duplicate.

We are reviewing our options here. There are some interesting security implications when moving something involves a Private Team.
