I'm looking to mirror my Ubuntu destop onto my TV by using my PS3. All done via wifi. Similar to the 'AirPlay Mirroring' in Mac OS X Mountain Lion. http://www.apple.com/macosx/mountain-lion/features.html#airplay
Is this possible? How would I go about it. To be clear, I don't want to share movies in particular, rather to send my screen exactly as I see it.
Looking at answers over the last five years (since the question was written) many say this is not possible:
However a product called PS3 Media Server has support for Linux using a Play Station 3 and might work. Be forewarned it hasn't been maintained since 2016.
