adobe flex air file preview

We have an AIR application which connects to a WAMP server. We support tiff images currently. We have a neat feature of previewing a tiff image( uses a URLLoader to read the bytes and opens the image in a popup)开发者_运维技巧 We want to extend this preview feature to other types of files too like "pdf", "doc", "movie file" etc.

Please let me know how can we achieve this in Adobe AIR.

also new docs are zip files, so google for AIR ZIP reader and then get RFC from MS for doc, and have a fun)
