Virtually all of our build configurations on our main server are just doing a checkout from SCM, publishing the source as an artifact, and running identical remote build configurations on multiple machines, waiting for each one to complete. There is already a request to add an option to have Trigger Remote Build block for completion (QB-335) so I don't need to request that here. All I need is a single step that can take a list of remote QB servers, and run Trigger Remote on all of them in parallel. This way I don't have to configure 20 QuickBuild Repositories and 20 Checkout steps from those Repositories to get a build running on all necessary machines.
