I'm not sure why it took me so long to get my XBMC installs connected with a single MySQL database, but now that I have, I am loving it!
In the media room, I have a Jetway ultra-small HTPC running OpenELEC 2.95.5 (Frodo RC1). This is connected via HDMI to a Denon 2808CI receiver which is connected via HDMI to a Samsung 55" LED TV (I know, it needs to be bigger and/or projected onto a 120" screen, but someone needs to convince my wife of that!).
I also have XBMC installed on (left to right) a Nexus 7 tablet, Alienware M14x laptop, Dell D620 laptop (for the guestroom) and Samsung Galaxy SIII. All XBMC endpoints connect via SMB to a Drobo NAS with 6TB capacity that currently houses 240 ripped Bluray and DVD discs that I have purchased over the years. It also features several TV show collections. We both love movies and TV, and have had several family members give us movies for birthdays and Christmas, and this is a great way to show them off for visitors!
I think this is probably the first pictures of its kind, even though it may not be the first actual "install". Please keep in mind that I do not use this for viewing video content while driving, but when the wife says "I need to run into [insert store name] and I'll be back in [insert arbitrary incorrect time frame]. You can wait in the car." This, my friends, is for THOSE moments!
There is also a Zotac Zbox ID40 in the family room, a RasPi in the master and also on the patio. All of these are also running OpenELEC 2.95.5 (Frodo RC1). I'll add a picture later.
I am running Mad-Max's awesome Confluence-MOD2 on all of my installations, along with BlueCop's Amazon, ESPN, Hulu and FreeCable plugins. I've certainly enjoyed XBMC over the years, and I hope my installation can provide others with the inspiration to share their setups! And of course, a HUGE THANK YOU to Team XBMC for all of their efforts.
