While you can use the Intuit Service to do the store exchanges, I find it faster and easier to use Dropbox to share the store exchange files. It is free and if you have any problems, you have complete control. Use the network file option when setting up the store exchange and set up the number of folders for each store in your dropbox folder. One for Store one, Store two, etc. Then you can set on the send and receive locations for the appropriate folder in dropbox. I use dropbox but any file sharing service will work.
