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.
