Yup, UK pound, 1.00 GBP	= 1.56323 USD give or take ;)

Yeh, something like that, so with a good software raid and some good
disks that shouldnt be a problem.

You could build a subsystem that took the HDCP protected content from
the BR drive and passed it in the clear to the video output.

One of the biggest markets I can see is a small "repeater" box that
sits between the output from the BR player and the screen, which
passes a non HDCP signal to non certified screens, eg older but high
ress ones. 

In the end, its not really about BR, its about any content, and
breaking the end to end encryption.
