Can BindField update in realtime?

Hi

I've been reading the documentation and searching the forum for BindField - is there any way that a child process activated via IPC can update (or be queried from) the parent process in real-time instead of having to wait for the process to finish?

This post - http://forum.k2workflow.com/viewtopic.php?t=53&highlight=bindfield - seems to suggest otherwise, but it's now over 2 years old and the answer may be different.

Thanks
Pete
