Not really. Vaxiin identifies a system going down via a dead man's switch, then goes out and grabs a screenshot out-of-band, runs OCR on it and matches reaction rules against the resulting text. Reactions might be ipmi commands, keystrokes, HTTP requests or a combination of the above. It might make sense to add an Ansible type of reaction as well, though I'm unsure of the scenario.
