Hmm - that would actually be a really good plugin for MythTV

MythVNC...

The power of opensource means that any settop box running linux could almost trivially add this feature for the cost of a wifi chipset.

Then any phone withi a wifi chipset could vnc-display it's pictures on the TV.

Of course it's too niche to do commercially - but if the phone and settop box were 'hackable' it would probably spread like wildfire

Sorry, daydream over.... back to your regular (non-wifi) programming.
