I want to share data on a project with many users, and wanted something similar to ArcReader. I like this software as it can be accessed from the server for speed, and therefore updated to other offices periodically.  If there was an option to add layers for users to mark up that would be awesome.

Is there a similar solution or approach for QGIS?

I realize that the users could just use QGIS but was hoping for something so straight forward it could be used virtually straight away.
