Reaching for the stars, finally - will the young ones among us get pics of Alpha C.?

The problem I see is getting enough power for a tiny probe to send information back, they are talking about something small, so no big power supplies, antenna arrays, solar panels or transmitters. No point geiing there if we get no information back.

That's another issue - but I have no good idea what kind of power is needed for such a transmission with a big space antenna on the receiving end.

Exactly Zebo.
 
Look at the New Horizons space probe for comparison.  The dish antenna on the probe is about 7ft in diameter, and a power output of 12 watts.  The probe can only transfer about 2,000 (2kbps) bits per second to earth so it's going to take until 2017 to receive all the data/images gathered as it went by Pluto.  When the probe communicated with Earth during it's Jupiter flyby the data transfer rate was 38kbps.  That is a helluva transfer rate drop in such a modest (relatively speaking) distance. 

The only way I could see this working is if 1000's of the little critters made the journey in one piece, and were able to communicate with each other like a hive.  At that point maybe they could arrange themselves into some sort of large antenna array.
