I do this with a multi-threaded AGI that authorizes credit card 
transactions. I create a thread to play "Please wait while..." and then 
process the authorization in the "foreground."

By the time the prompt finishes I usually have my authorization response 
so the process appears instantaneous to the caller.

Thanks in advance,
