I have to say that, while the update to version 1.9 has been delayed for three hours, which will likely cause my fingernails to become practically non-existent, looking at the video by Ben Linden regarding camera controls - a sizeable Quicktime file - gives me hope that I will be able to tailor the view inside of the lighthouse to make it perfectly possible to view the interior, rather than the visitor's camera bouncing through stone walls in an unfortunate manner. This should be an extremely interesting thing to play with, in any case. Top show, Linden Labs! (At least I say that now, on the assumption that other problems will not be broken. It does not do to take a negative outlook on these things when one has no hope of actually affecting the outcome.)
I foresee that it might perchance become used a little much generally, but hopefully the necessity to script it will restrain some of the more egregious uses. And of course, one can always refuse to allow an interloper to control one's worldview.
Edit: Well, looking at the details, it appears that only attachments and vehicles can control the camera as yet, which is something of a blow. But I'm sure something will arrive at some point. Meanwhile, there are other things to consider.
