I think a tool which is basically yet another webchat-solution but tries too push their omnipotent app onto you, no matter what, has some issues beyond security. All the "user"-friendly execution looks like some 2002 nigerian adware. I guess userfriendly is really easy if your app can never be closed (not sure about that), can't be uninstalled and you nag the user twice to actually really start that app before allowing to use a runtime under his/her control.
