How to build a test running multiple test groups concurrently, but showing I/O data of all test groups on the same webpage?

We are building a manufacturing test station, which needs to run test groups over 4 modules at a time. Those 4 test groups share couple of instruments so they will need to take turn on those test cases; but other than that they have their own resources for remaining test cases. All the I/O data, like user input, prompts and logs, test results, of 4 test groups need to be displayed and refreshed on a single webpage. How does openhtf support such a use case? Any suggestions are highly appreciated.
