Easy questions from a beginner

Hi,

My company has a BO XI 3.0 platform and I'm asking myself few questions about Crystal report integration to this platform:

1) Is it possible to store Crystal Report in the BO Server when I only work with CR 2008, or I need the product Crystal report server ?

2-3) if I store Crystal Reports reports in the BO Server (Format of these reports: normal Crystal report format), can other users who haven't Crystal Report Rich client in their computer view this reports threw Iview? If not, must they install the Crystal Report viewer?

Thank you very much!
