It's very apparent that the word is getting out. At the Stephens Fall conference about 2 weeks ago, Mela Sciences Inc. CEO Gulfo was asked about competitors to Mela, with the statement inside the question being something like: "There has been some noise about competition -- I think Verisante is the most well known competitor out there -- ...."
Gulfo proceeded to stumble through his answer like he often does, citing that the greatest hurdle to competitors is the PMA process, etc.
If you are interested knowing more about "competition" to the Aura, it's worth a listen to the entire webcast.
If you are only interesting in hearing the part where Verisante is mentioned, scroll ahead to just before 31:00.
