So we need a free software effort to produce some kind of machine learning/statistical analysis tools that would not be sold but merely used by whoever wants them. The user should be a medical professional using the tool as an aid much like a reference book. A good doctor doesn't take the book as gospel (at least my GP doesn't) but weighs what it says together with the specifics of the case and so on together with his or her own experience. So perhaps a grassroots start could be possible.

Of course the major stumbling block of access to good data remains.

It doesn't need to be free - good medical reference books aren't, either.
