Hey, Shaun. This is Scott. Steve invited me to do the Logic Node tutorials, so I'm glad you liked them. I've found that Logic Node can be temperamental at times -- for example, the 'lost connection' errors that pop up from time to time. It would be great to have some more detailed logging of what's going on. Apple?!? As far as starting the node process for multiple logins, you might try placing Logic Node as a startup program for each user account. (System Preferences->Accounts->Login Items). As long as your kids don't quit Logic Node, this may work. Try it out and let me know.
