I would not accept anything with a short seed (say at least several
hundred bytes) as acceptable. Other than the believed cryptographically
strong Shamir and Blum-Miccaeli (sp?) procedures, which are extremely
costly, I know of none. The problem is at least moderate-term independence,
and correlations, periods, etc., do not answer the question.
Also, most generators produce "real" or other lengths than the entire
word. There are may situations in which a random bit stream is needed.
The others can be cheaply obtained from this, but not vice-versa.
