Unfortunately, your answer regarding Private SNPs is incorrect. The short aswer would be that the SNP must have at least two men with sufficient different haplotypes.

Matthew's question was not what criteria ISOGG uses for including an SNP, but how the testing companies use the term "private SNP", and at least with respect to Full Genomes, John's answer sounds correct to me. What is not known at first is how private the SNP will turn out to be. Some will be very private and confined to an individual or his close family, while others will eventually be shown to define new sub-haplogroups. And Full Genomes does indeed assign FGC names to new private SNPs without waiting for other instances of the SNP to be found.
