Take a look at: http://www.mygrid.org.uk/usermanual1.7/workbench_windows.html#ame_processors (towards the end of that page "3.1.1.6.7. Configuring multithreading"). If you are invoking the service within a set of iterations then this will invoke them in parallel. Technically speaking the services are still called synchronously, but on multiple threads.
There is similar functionality in Taverna 2.1 beta, that will be included in the next beta version to be released very soon. In Taverna 2.0 this wasn't configurable in the user interface.
