It’s easy. You can request the registration of any number of names on a
single bus connection
<https://dbus.freedesktop.org/doc/api/html/group__DBusBus.html>. Then,
when you receive a message, you call dbus_message_get_destination()
<https://dbus.freedesktop.org/doc/api/html/group__DBusMessage.html#gaac65c926e6253e49aa689b4f032fad45>
to determine the exact name it was addressed to, and dispatch your
method-call handling on that.
