Haven't read the whole thing,but here goes. Local college hires firm to do a total of 50 rooms with crestron some duplicated, but a bunch of different systems. all are independant of each. mostly tabletop panels some inwalls.

so it is now 6 months after they moved in and there are some things they would like to fix that no one realized didn't work. original firm won't come out and fix, and won't hand over code at all. so now they are screwed.
