Rockwell has a software package called FactoryTalk View Point, which allows displays that are developed in SE to be "published" to a web server. Then, anyone with access to the webserver can see the live process graphics. I have used them in plants where management wants to monitor the process, but not control anything. It may be possible to control also, but I have only used view only applications. I know a license is required, and you can have many seats.
