Hi
The Camera will run out of the Box.
To use pan and tilt, i suggest you compile "Palatir" for the WL500g which has streaming video services avaliable over a linux, windows or java binarys which can controll pan and tilt of this cam.
I have no Spehre, but wanted Palantir on the 500g. Lazyness has stoped me from this at the moment, if you are a bit experienced with linux, i think you can do it yourself.
