Right, that's one possible solution. Another is to use an algebraic threshold scheme. For example, you can support M-of-N threshold schemes with 2 <= M <= N with N up to 15 if you compute over GF(2^4) modulo the irreducible polynomial x^4 + x + 1 using nibble arithmetic. In any case, the quality of random numbers is crucial to the security of the data.
