I like this idea and it would be great to have a viewer for the following apps as well:
* Adobe PDF (.pdf)
* Adobe PostScript (.ps)
* Microsoft Word (.doc, .docx)
* Microsoft PowerPoint (.ppt, .pps, .pptx)
* Microsoft Excel (.xls, xlsx)
* OpenOffice Text Document (.odt, .sxw)
* OpenOffice Presentation Document (.odp, .sxi)
* OpenOffice Spreadsheet (.ods, .sxc)
* All OpenDocument formats
* Plain text (.txt)
* Rich text format (.rtf)
