Sounds cool. I'd probably prefer to use >> and/or << as operators, though, if for no other reason than they're already overloaded by iostreams, so as library users we're used to expecting that overload. >>= isn't similarly overloaded, so it's something of a surprise. operator() isn't bad either, but << or >> are better visually.
I wonder if a different operator (maybe || ?) could be used to create trees? Or maybe that gets confusing. Your example would become:
((video_generator >> differencer >> flipper >> analysis >> database >> display1)
I think this is clearer than your proposed syntax:
(video_generator >> differencer >> flipper >> analysis >> database >> display1)
because the latter implies that display2 gets input from the parenthesized sequence in the middle, which isn't the case (if I understood it correctly).
