Run icamsource as a service. There's a post on here that details how to do it. The only downside...you can't access icamsource unless you stop the service and then start icamsource from the Start Menu (instead of as a service). But as a service, it doesn't show up in the system task bar. Like you, I searched for free programs that would hide icons in the system tray, but never did find one. Bummer. But I do run it as a service, and it works great!
