We have been using this technique for years.  We even posted the application we use to do this task in RevNet.  I believe I need to update that file now that I think of it.  But in short, we use our ISP to gather orders.  Our client software sends a request for a key.  Our local computer in the lab just pings the directory on the ISP every 4 seconds and downloads all the orders in that given directory.  The heavy lifting and database work is done on a computer in the lab.  The key is then sent back up to the ISP where the client computer is checking in for the result of that work every 4 seconds.  The whole thing works out nicely and we keep our CPU usage low.
