VPN

I realize that this is probably not the proper list for this, but I am hoping somone can point me in the right direction. We have a customer who wants to setup VPN between their location and a remote site. Both sites will be running WIndows NT 4.0 the setup is no problem, I am wondering how much bandwidth they are going to need. They are only going to be using an automotive DOS based inventory system between locations and an occasional e-mail. If anyone could let me know how to calculate the bandwidth or give me some pointers I would appreciate it. Thanks...
