Have you got a story to share about on-premise SharePoint and Office 365 integration?

Thought it’d be great to start a discussion about the options, challenges and configuration required to integrate on-premise SharePoint with 365 (or even private clouds such as Fpweb.net).

What are the main areas to think about (e.g security, authentication, performance, latency …) ? If you can share your experiences, we’d love to hear about them!

Thanks

Mark
