Thank you very much for your entries. However, they are a little too obvious/literal interpretations of what only one part of the site is about. I am looking for something much more abstract but that somehow still manages to get the whole message of what the site can do across.
Any preference on style of fonts? sharp, rounded... you looking for a more web2.0 looking 3dish logo?
There are some more literal examples ranked higher, so what main things would you like to say with the logo if not the cam, multiple users, currency etc as you've mentioned...
