There have been calls for an interstellar probe although that would of course be an incredible effort.  Here is a bit more on that notion from wikipedia:

The announcement of the planet’s existence sparked renewed interest in Alpha Centauri as a potential target for an interstellar probe, including enthusiasm from mainstream astronomers.  Debra Fischer of Yale opined that “If you were going to send a spacecraft anywhere, or a probe anywhere, that’s where you’d go first.” 

Planetary scientist Greg Laughlin admitted that such approaches were “speculative and farfetched so far”, and noted that with current technology a probe sent to Alpha Centauri would take 40,000 years to arrive, but expressed hope for new technology to be developed to make the trip within a human lifetime.

Well that is a bit too long 😉  Perhaps even listening or sending S.E.T.I. signal would make sense first?
