I'm not quite sure what to make of Avatrian's Peek360. You enter the coordinates of a location in Second Life, a brief description and your email address and, if things are working right, about 10 - 20 minutes later you get a link to a virtual 360° view around the coordinates. The results are embedded Flash clips that are pretty damn good. I'm not sure how they pull this off technically (hey I'm only semi-literate on this) or whether it can go into private access regions, but it was fun to play with. Here are two clips from inside my house in Second Life.

So what would you do with something like this? Spy on your neighbors remotely? Create virtual tours for selling real estate in Second Life? Make people dizzy sick from watching them?
