For "standard" Shamir secret sharing you use a new random polynomial for each secret you want to share (including when you use Shamir secret sharing in SMC). I.e., you would use different polynomials for each secret. Note, that Shamir secret sharing does not directly work on "words" but rather elements of some field. You would have to translate your data ...

Let us first consider the problem without involving Shamir secret-sharing at all. Suppose that $n = 140$ and that the secret $\sigma$ is a 140-byte Twitter message. The space is thus restricted considerably, from all possible $256$ byte values to the printable characters permitted to be used in Twitter messages, and the distribution in this restricted space ...
