Thanks guys, running multiple instances of DHIS2 Live is definitely the
easiest to set up and teach. In fact, I think there may be quite few
instances where Tomcat is needed on Windows. And I don't even think I need
to worry about dhis2.home - since everything is confined to the folder where
dhis2-live.exe resides.

As Ola pointed out, the remaining and important issue is the automated
startup after a power cut. Found some info here, grateful for further ideas.
