As a simple rule of thumb, most voice over internet connections suggest 16-32K of bandwidth. If you're going to push voice for 15 people with QoS then dedicate 480K, for 20 people get 640K.
If you will not have QoS on the connection, then beware of Xbox or other gaming terminals and other devices that suck up bandwidth. The people on those devices may become very unpopular.
Other than bandwidth sucking applications, you should generally be able to get by on 32K per device connected (computer, telephone, email reader) and provide reasonably fast web surfing and email access alongside decent VoIP.
I'd love to know how this turns out for you as I have several friends over there also interested.
