[Live-devel] Attach sink to multiple sources

The best way to do this would not be to define a new type of sink, 
but instead define a new type of source - i.e., a subclass of 
"FramedSource" - that would, as usual, feed into a single sink, but 
would read from multiple sources, as desired.

More specifically, your new "FramedSource" subclass would perhaps 
take the (multiple) input sources as parameters to its constructor 
(and its "createNew()" function), and would implement the 
"doGetNextFrame()" virtual function by reading from the appropriate 
input source.
