Stream Tubes wrap a TCP socket connection between two participants. This could be http, or any protocol of your choice. That's good for transfering files to a particular participant. D-Bus Tubes are more event driven, and signals go to all participants in the shared activity session - so a way of updating everyone at once with a small change. You can certainly use both. See http://dbus.freedesktop.org/doc/dbus-python/doc/tutorial.html#data-types for how the types work in dbus-python (and hence D-Bus Tubes). You can send binary data, and data structured in lists, tuples and dicts. Feel free to ask more specific questions...
