Well we do, I just never really noticed that they do repeat. Believe it
or not I don't watch much TV... there's too many commercials =D. After
further reviewing the Sky Watch you are very much correct there is much
more repetition than I had initially thought when compared with the FTA
channels. I guess the issue of malicious keys would be more significant
than I realized, certainly an issue to be dealt with if on
line-collaboration was ever implemented.

To put it shortly, possibly. It would depend on how they are
structured, I will have to look into this further.
Thanks for all the feedback guys, its good to have other people pick
over an idea to find the flaws =D Stitch in Time and all that.
