If you're doing video and audio push, too--and not just the GUI--you'll
probably have tons of CODEC issues (i.e. your Samsung phone is happy to
do Ogg, but your Samsung TV refuses, so DLNA doesn't let you play those
files through your TV--and possibly similar issues with the
very-common-in-MythTV-recordings MPEG-2). And, it seems that DLNA will
never be user friendly, and will always require way too much technical
expertise.
Another option is to check out:
Miracast: http://en.wikipedia.org/wiki/Miracast ("open" (not buy-in)
standard to replace AirPlay)
Wi-Fi Direct: http://en.wikipedia.org/wiki/Wi-Fi_Direct (underlying
transport for Miracast)
DASH: http://en.wikipedia.org/wiki/Dynamic_Adaptive_Streaming_over_HTTP
(standardized replacement for HLS)
It seems to me that DLNA is something that promises much, but delivers
little (due to the lack of good implementations (or differences in
existing implementations)/lack of enforcement of "must support X CODEC,"
etc.)--not to mention the "club members only" approach to the standard,
enforced by the cost of getting the specs so you can implement it.
