The nice thing about having a native client is that we (Screenhero) have full control over latency (well, outside of network issues of course!) and responsiveness, as well as those deep hooks into the hardware to make the multi-mouse magic happen. Our goal is to make /any/ app collaborative, without requiring developers hook into our API. I am curious what kind of apps you have in mind that might need to give hints to Screenhero? Give it a try, we think you'll find our active-cursor algorithm quite good—and if you don't, we want to hear your feedback!
