I am looking for a way to allow users without the Office 20XX package to view documents in a Sharepoint 2007 document library. Ideally, it would allow them to open the documents directly from the document library, but if it's implemented through a web part where you select documents and such, that would be great as well.
It is not a necessity that people can edit the documents, they simply need to be able to view them. I am looking for something that opens both Word, Excel and PowerPoint files, but a solution that only covers one type still has interest.
