Customer Chat and Portal app

With so many customers going mobile, we would like to see the option of a customer app that will allow the customer to chat and view ticket status on the go. I know that they can just visit their customer portal from a browser to view ticket status, but I would like a chat option. We currently support our distribuitors in over 40 countries and many are field technical representatives. I would be nice if they can go on their mobile devices and start a chat session with us without having to access a perticular website. We don't want to add chat access to our public website as this would mean that end users would be able to contact us directly instead of going through their local authorized dealers. Please add this valuable feature,
