That's an impressive CV! but what you have to take into consideration
is this is a server forum and I suppose rightly or wrongly a certain level of understanding is assumed
We can only ascertain your level of understanding by the questions and answers you posted
and you're judged on those replies. as far as I can see you didn't understand the difference
between samba and apache. You or anyone else may be highly technical but still know little about the workings of OSX server, it's not a crime or attack on your technical abilities. You or anyone else may be highly technical in their field but a complete novice in another, it's not an attack or insult, it's just an observation.
it's starting to sound like you need a media center like xbmc, plex or mythtv
all of these can store your pictures, movies, music all can stream round your network
ether via DLNA or a front end. xbmc and mythtv support airplay, not sure about Plex
all are free, most have front ends that will run on most OS
there is even a xbmc version that will run on a raspberry pi, a cheap and silent front end
most of these also have remote control apps for android and IOS
with the correct video encoding and DLNA player you can also watch video on your android or IOS device
steamed from your media centre
