Hi. I am developing a small portal with webcams for tourism. For each camera, which is inserted into a K2 item, I would like to see not only how many total visitors I had (which is already possible), but also how many visitors I'm having at the moment (live). Could anybody suggest a method to achieve this?

Hi. What you are trying to do is not that easy. I strongly suggest that you hire a ( really good ) programmer to implement this for you since i don't think you can find an extension for this.
