Just a few quick ideas I had for this: There is already a demo modus.
Perhaps you can recycle this and let gkrellm poll the designated server
from time to time. If it answers, restart gkrellm using the input from
the server. Or gkrellm may always save the current configuration (i.e.
the running monitors) at shutdown and these are restored at startup
until the server can be connected.

These are just some thoughts without having looked into your code, so if
this is dumb just ignore it.

That's a good idea. There's even no need for a variable subsitution. The
script itself can check if the server is running (ping it, search for
the corresponding pid of kvm or something similar) and take the
appropriate action.

That's true.

That would be great, thanks.
