Second Life Metrics.. whatever next ?!

I've just found a company called Maya Realities whose sole purpose is to provide metrics to sim owners in second life showing things such as number of visitors per hour, whereabouts avatars teleport into the sim, how long they stay etc. It's amazing (I think) that companies are providing such things for a virtual world - but then again, with big businesses such as IBM, Sony and Apple getting involved in Second Life, there will be a need to provide such statistics.
