This does work actually and its pretty awesome. Took a bit of time to figure out. First off, you need to remove the commas after the "publish": option in the example above. You can see my fork here. You can also view my example here

I noticed in the sensu-api.log that remediation was POSTing to the API using the hostname of the affected server as the subscriber: {"timestamp":"2014-10-06T18:46:16.656712+0000","level":"info","message":"POST /request","remote_address":"127.0.0.1","user_agent":"Ruby","request_method":"POS
T","request_uri":"/request","request_body":"{"check":"heavy_remediation","subscribers":["hostname.example.com"]}"}

I changed the client to subscribe to hostname.example.com and everything started working. I created a gist outlining the steps to get this running.

As a side note: Pretty clever use of the API to accomplish remediation. Great work!

Thanks alot @seth-paxton, the reason why its been failing was because of the subscriber pointing to the client name. I just added it and worked flawlessly.
Thanks alot.
