openmash vic has this capability right now -- it will switch
sessions if it receives a "SET_SESSION" message on the mbus.
there's a python implementation of mbus at www.mbus.org.  i
haven't tested its interoperability with the mash implementation
but in theory, all the pieces are there so this could be added
pretty easily to the various Video*Service's.

as i understand the current ag architecture, it wouldn't really
be possible to take advantage of a multi-input vic since there
is a 1-to-1 mapping of "resources" (i.e., video capture devices)
to node services.  if that is incorrect, i'd be interested in a
clarification.
