Running dependent VI front panels in parallell

I'm designing an extensive LabView program in which I want to be able to open several subVI front panels that all run independently (ie it should be possible to work in all open windows). This I have successfully accomplished by using Invoke Nodes and setting "Wait until done" false. My dilemma is that the subVIs are dependent on data aquired in the top level program and I don't know how to pass this dataflow to the subVIs. Can anyone help me?

Thanks

The options for passing data to independently-running loops is wide open ranging from standard globals (a bad idea) to LV ver 2 "globals" (much better) to remote VI calls (very slow when talking to your own machine). Email me directly and I'll send you a simple example. BTW this is an excellent way to structure a program--I use it all the time...
