I find your examples unconvincing. How many emails do you really get that are so urgent that they couldn't wait an hour? Why can't your babysitter text you (or, just IM on your smartphone)? Why are you the only person who can fix said critical bug (if it's fixable through the CMS, others should be able to handle it, if not, well, why are you running such terrible infrastructure when there are dozens of mature platforms?). Also, for things that are legitimately small and quick, it's surprising what you can get done with an SSH client on your phone - if it needs more than that, you're likely going to miss the rest of the lecture anyway, so why not leave?
