Sure, you could do a mouse jiggler, but I'd just have something that
periodically calls SetThreadExecutionState (ES_SYSTEM_REQUIRED) while an
ssh session is active.  The remarks say "The system automatically detects
activities such as local keyboard or mouse input, server activity, and
changing window focus. Activities that are not automatically detected
include disk or CPU activity and video display."  It seems like ssh
keepalive should count as server activity, but apparently not.
