I often send sharing links to clients without access to Microsoft Office or document viewing clients. I would love to have the option to allow guest users to preview Word/Excel documents within the browser using one of the available document viewers (Google Docs Viewer, OpenOffice, etc).
As a bonus, it would also be a nice feature to allow guests to edit a document with Google Docs Editor, Zoho, OnlyOffice, etc. and be able to control guest editing permissions.
