I have requirement of documets uploaded on sharepoint 2007 server in any document library is not downloadable using digital rights management.
1. DRM (IRM in Sharepoint) is a very powerful solution that can restrict what is done with the items from sharepoint lists when they have been downloaded. You can prevent printing of downloaded documents, or excerpts being taken from them etc.2. You can do this without using IRM. Sharepoint has a solid permissions/security model which you can use to stop download of items in the first place. If that's what you're after then IRM might be overkill.Have a look at this overview;office.microsoft.com/.../HA101280011033.aspx
