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...
Might you like any of these styles that I created on another contest:
