I see this thread is somewhat dated … but wanted to share some info around Piwik and Twilio. I’m a new Piwik user/developer and have been really impressed with Piwik’s capabilities. I recently blogged @ [url=https://developer.ibm.com/bluemix/2014/07/03/getting-started-piwik-ibm-bluemix/] about how users can deploy Piwik onto IBM’s new Platform as a Service Bluemix platform. [url=https://www.bluemix.net] In the post, I demonstrate a way to run Piwik on Bluemix and leverage the SendGrid and Twilio SaaS services provided by the platform. Regarding Twilio, I’ve written a SMS Provider that leverages Twilio’s PHP Helper library. This code should be useful, independent of where Piwik is running and can be found in the article. If its worthwhile, I’d also consider contributing it back to the project.
