Interesting, and clever!

But how do they do that? Since the app can’t be running at the time it is moved 
to the trash, the code can’t be in the app itself. Which means they must 
install *another piece of code*, probably a daemon, which is running all the 
time; which would be necessary anyway for a security watchdog of course. Then 
does this but of code  uninstall itself? Possible I guess, the daemon file 
itself is not open when it is running so it could be moved to the trash and the 
daemon wasn’t killed it would just stop running the next time you reboot.

Of course for an LC standalone to use such an uninstall strategy you would need 
and Installer; and I don’t think it is really appropriate to have an ordinary 
app to have a daemon running all the time.
