I maintain a small system in a small club. Two 46" TVs each have their individual HD receivers, and the 70" TV has its own HD receiver. Due to the simplicity, the system runs from one non-SWM dish. The club is private and as I recall, the monthly bill is based on the # of dues paying members. The installation fee was IIRC, free for the dish and first HD box, and $99 for each of the 2 additional receivers. The facility had never had any cable or satellite service before.
The floor plan has the TVs well seperated, so they all work from the same IR remote, and all the TVs are the same brand too. Kept it simple for the staff and they appreciate it.
Only trouble they have ever had was during a rainy period and they called me for frequent pixellation. They had new shingles installed and the roofers had noodged the dish just enough to make it fussy about drizzle. Re-aimed and every one was happy.
I've seen a rack of at least 40 D* receivers at a restaurant called Indigo Joes. The restaurant is long gone, and I wondered if all the big screen TVs bankrupted them, LOL. Amazing site to see all those receivers!!
I also maintain a Senior TV system with around 40 receivers, but they each run a SD modulator, and that would not be appropriate for a bar filled with big screens.
