Yes, you can use PSEXEC any time and call it from VisualCron. What PSExec is doing is installing a remote service that executes.
While we have this in mind there are two things we need to consider first:
1. how we should implement this, as separate agent or via Server installation.
2. how do we handle licenses for this? One of the problem is that Remote Execute with agent conflicts with Server license installation
The question is how many remote servers you want to execute on?
