maven in parallel

Yes, this is an option indeed, however, I want to use maven 3 parallel feature, but the soapui plugin fails since it is not thread safe.
The reason I want to use the maven's parallel capability is that my projects are arranged as a multi-module maven projects. I want to run each module in parallel.
Using Soapui threads to run all test suites in a project in parallel is over-kill.

Any chance having a thread safe plugin in the foreseeable future?

Thanks
