Very small. There are lots of 100-300 Byte Pieces. A 20kByte Piece would 
be very very big and does not really make sense.
But it would also be possible to send bigger Pieces - one per minute for 

If every atomic data piece is sent independent there can be hundreds or 
maybe tausands of messages per minute.
