Glad I missed that tour bus! I'm vague on what the prisoners know to begin with. I believe the following is true, please correct me if I'm wrong.
Here's what WE know:
(1) the prisoners are occupying 7 positions in a linear formation (although each is individually facing in any direction, given in the OP)
(2) each prisoner is wearing a different colored blindfold
(3) reading from one end of the line to the other, the colors are ROYGBVW
What do the prisoners know?
(1) Do they know they are in a line?
(2) Do they know where they are in the line?
(3) Do they know the orientations of their immediate neighbors?
(4) Do they know the colors of their neighbors' blindfolds
(5) Do they know which end of the line wears R?
I'm presuming that 3,4, and 5 are No.
What about 1 and 2?

There's a lot I don't understand, just in terms of terminology.
As an example, OP says that "Chi has 2 hostages facing backward on his right, 3 sitting down on his right. "
Am I to believe that there are EXACTLY 2 hostages facing backward on his right, and any other hostages on his right are facing forward?
Or that there are AT LEAST 2 hostages on his right facing backward?
I'm presuming that this gives me no information about how many backwards-facers are to Chi's Left.
