[Jeremy Palmer <>]

We do use owamp for testing between our toolkit nodes (mesh config).
However, sometimes its useful to setup a pingER test when doing customer 
troubleshooting since normally a customer will not have an owamp responder in 
their network. Its really more of a nice-to-have feature for us. It would be 
awesome if this can be incorporated in a future release.

Thanks!
