It's a remote service ; you are presumably streaming off rapidfire
requests at it.   Sometime later, responses come back and presumably
are processed by your secret code.
It might all stop working if you exceed the limits -

You probably want to introduce some timing ; do you really need
continuous update, or only every X milliseconds?  How about only if
the mouse lingers in one place for a while?
